In other embodiments of the present invention, as shown in Figure 2, the two ends of raised section 1 are connected to end straightway 13, and one end that the distance raised section 1 of end straightway 13 is far away and straight line section 2 are fixed by fixed connecting piece (as metal sleeve 3).Thus raised section 1 can be formed " wave inception bar dowel " with the end straightway 13 at these two ends, raised section 1, the two ends of being somebody's turn to do " wave inception bar dowel " respectively can connect a linear pattern reinforcing bar and straightway 2, thus form " the wave inception reinforcing bar " according to the embodiment of the present invention.
In this embodiment, as shown in Figure 2, fixed connecting piece can be metal sleeve 3, thus convenient fixing, firm.But the present invention is not limited to this, the straightway reinforcing bar at such as " wave inception bar dowel " and two ends also can by weld or alternate manner is fixed.
Shown in composition graphs 3, shown in Fig. 3 according to the embodiment of the present invention " wave inception reinforcing bar " deformation when being subject to larger external force, from the schematic diagram of Fig. 3, we can find out with cleaning, the distortion of " wave inception reinforcing bar " takes the lead in occurring in " wave inception " place (i.e. raised section 1 part), along with the change of external force is large, " wave inception " part is by stretching gradually, substantially the variant of generic linear steel bar is there is after stretching again in this part, therefore traditional line steel bar is compared, according to the process that " the wave inception reinforcing bar " of the embodiment of the present invention is straightened due to many " wave inception " parts, therefore there is deformability more better than generic linear steel bar, make this reinforced concrete structure can be out of shape better to absorb seismic energy in earthquake, effectively prevent building collapse.
Below in conjunction with Fig. 4, Fig. 6 and Fig. 8-Figure 11, the structure of separation sleeve 104 is described in detail.
As shown in figures s-11, as preferred embodiment, raised section 1 entirety is accommodated in corresponding separation sleeve 104, in other words, separation sleeve 104 is by covering place completely of " wave inception " part, making separation sleeve 104 effectively raised section 1 and concrete to be kept apart like this, ensureing that raised section 1 can fully be out of shape when there is the natural calamities such as such as earthquake.
In certain embodiments, as shown in Figure 8 and Figure 9, separation sleeve 104 can be U-shaped structure, but is not limited thereto.Such as, in further embodiments, as shown in Figure 10 and Figure 11, separation sleeve 104 can also be cannula-like, and this cannula-like structure can have but be not limited to ellipsoidal structure.
According to some embodiments of the present invention, separation sleeve 104 can be FRP (fibre reinforced composites, fiber reinforcedpolymer/plastic are called for short FRP) separation sleeve 104.This FRP separation sleeve 104 can be formed through certain process combining by fiber and matrix, has high-strength light, the excellent characteristic such as corrosion-resistant.Alternatively, FRP separation sleeve 104 can be carbon fiber (CFRP) separation sleeve 104, glass fiber (GFRP) separation sleeve 104 or aramid fiber (AFRP) separation sleeve 104 further.
To sum up, according to the concrete-bar component 101 of the embodiment of the present invention, by arranging for isolating concrete separation sleeve 104 at " wave inception " place of " wave inception reinforcing bar ", " wave inception " is in can by fully stretching when being subject to larger external force, ensure deformability, avoid " wave inception " place and concrete directly to contact and pressure is produced to concrete and causes " wave inception " part to collapse from beam, and then cause this cross section to occur larger crack, affect the supporting capacity of plastic hinge.
Below the rc-frame-beam structure 1000 according to the embodiment of the present invention is described in conjunction with specific embodiments.
In certain embodiments, as shown in Figure 5 and Figure 6, rc-frame-beam structure 1000 can comprise column 102 and concrete-bar component 101.Concrete-bar component 101 is arranged between two adjacent columns 102.Column 102 can be vertical setting, and concrete-bar component 101 can be arranged between adjacent two columns 102 orthogonally, and column 102 can adopt reinforced concrete structure equally.
In certain embodiments, concrete-bar component 101 can comprise reinforcing bar 100.In a further embodiment, concrete-bar component 101 can also comprise above-mentioned separation sleeve 104.
Thus, according in the rc-frame-beam structure 1000 of the embodiment of the present invention owing to being configured with " wave inception reinforcing bar ", at reinforcing bar wave inception section, beam effective height reduces at least to a certain extent, and anti-bending bearing capacity is weakened.Thus this cross section easily forms plastic hinge under geological process, simultaneously because the deformability of reinforcing bar strengthens, the turning power in cross section is enhanced, and can ensure the safety of plastic hinge, reaches " strong column and weak beam " energy consume mechanism with this.
Further, as Figure 4-Figure 6, concrete-bar component 101 can comprise at least two groups and between the upper and lower every setting.Such as, in certain embodiments, concrete-bar component 101 can be divided into one group of bar construction and below one group of bar construction above.Alternatively, as shown in Figure 4, often organize concrete-bar component 101 and comprise spacing side by side and arrange and the multiple concrete-bar components 101 being in same level height, as every placing of reinforcement assembly 101 comprises two bar constructions, as shown in Figure 4, but be not limited thereto.
As preferred embodiment, shown in composition graphs 5, the raised section 1 being positioned at one group of concrete-bar component 101 is above opposite to each other on vertical with the raised section 1 being positioned at one group of concrete-bar component 101 below.Further, the raised section 1 being positioned at one group of concrete-bar component 101 is above protruded downwards and to be positioned at the raised section 1 of one group of concrete-bar component 101 below protruding upward.
Thus, reduce the effective height of this " wave inception " section beam, while weakening its bend-carrying capacity, its shear resistance capacity remains unchanged.Under daily load action, this place's moment of flexure is less and shearing is comparatively large, thus can ensure that its bearing capacity is enough.And under seismic loading, the moment of flexure suffered by this cross section is comparatively large and its cross section bend-carrying capacity is less, therefore easily forms plastic hinge, and then reach " strong column and weak beam " energy consume mechanism.In addition, the reinforcing bar at " wave inception " place can be straightened under seismic loading, and have extending and deforming capacity more better than general linear pattern reinforcing bar, " plastic hinge " that therefore formed at this place has better turning power.
As shown in Figure 4, in one embodiment, separation sleeve 104 sheathed on raised section 1 is U-shaped structure, is wherein positioned at the opening down of the separation sleeve 104 of the U-shaped on raised section 1 above, is positioned at the opening up of the separation sleeve 104 of the U-shaped on raised section 1 below.Like this, be convenient to separation sleeve 104 to be sleeved on " wave inception " place on the one hand, on the other hand, concrete can be kept apart with " wave inception " place by U-shaped separation sleeve 104 better, and protection " wave inception " fully can be out of shape when stressed.
Because the reinforcing bar 100 in above-mentioned rc-frame-beam structure 1000 has " wave inception " structure, " wave inception " structure stress can be straightened distortion, therefore " wave inception " structure should can form distressed structure, in brief, concrete-bar component 101 be configured with distressed structure.
The setting position of distressed structure 1 is related to the formation of plastic hinge in beam, inventor is by great many of experiments and industry experience discovery for many years, distressed structure 1 easily forms plastic hinge at beam when being arranged in the minimum place of the moment of flexure of rc-frame-beam structure 1000 under vertical load effect, thus can fully be out of shape absorption energy.Certainly, the contiguous minimum place of the moment of flexure of this rc-frame-beam structure 1000 under vertical load effect of distressed structure 1 also can reach preferably effect.
Shown in composition graphs 7, from according to the rc-frame-beam structure 1000 of the embodiment of the present invention at vertical load (F
1) and horizontal loading (F
2) under bending moment diagram to carry out contrast known: frame beam structure is at vertical load (F
1) under effect, be close to zero in the moment of flexure at reinforcing bar " wave inception " place (i.e. distressed structure), be subject to horizontal loading (F
2) time, the moment of flexure in this cross section becomes a higher value.The concrete beam of configuration " wave inception reinforcing bar " is mainly bearing vertical load at ordinary times, and as structural weight per square meter and Live Loads on Floors in Buildings etc., at reinforcing bar " wave inception " place, moment of flexure is less, though its section bearing capacity is little, but still is enough.And when meeting with earthquake, the moment of flexure in this cross section will increase a lot as shown in Figure 7, compare other cross section, this cross section due to bearing capacity weakened, can take the lead in surrendering formation plastic hinge, thus it is machine-processed to reach " strong column and weak beam ".
Further, in order to increase the intensity at distressed structure 1 such as " wave inception " place, can also arrange at distressed structure place and strengthening structure 103.Be understandable that, strengthen structure and not only can be arranged on " wave inception " place, other position of reinforcing bar 100 can also be arranged on.
Thus, because " wave inception reinforcing bar " has outstanding deformability, this cross section has better turning power after surrender, adds that the reinforcement structure example of configuration is as stirrup 103, the turning power in " wave inception " cross section is got better protection.
According to some embodiments of the present invention, strengthening structure can be stirrup 103, and concrete-bar component 101 is fixed by this stirrup 103.
In certain embodiments, raised section 1 place configuration encryption stirrup 103, in other words, stirrup 103 density that raised section 1 place is arranged is relatively large.
As preferred embodiment, as shown in Figure 4 and Figure 5, be greater than the density of setting of the stirrup 103 adjacent two raised sections 1 to the density of setting of the stirrup 103 of nearest raised section 1 from column 102.In other words, shown in composition graphs 4, left side column 102 is greater than the density of setting of the stirrup 103 between left side and raised section, right side 1 to the density of setting of the stirrup 103 at raised section 1 place in left side and right side uprights 102 to the density of setting of the stirrup 103 at raised section, right side 1 place.Thus, " wave inception " cross section, place has better turning power after surrender, and add the stirrup 103 of intensive setting, the turning power in cross section strengthens further, thus the seismic energy that can fully dissipate.
Further, the stirrup 103 on reinforcing bar 100 can adopt 135 ° of crotches to be fixed, and the stirrup 103 at separation sleeve 104 place can adopt 90 ° of crotches to be fixed, but is not limited thereto.Meanwhile, separation sleeve 104 axial two ends place respectively can arrange a stirrup 103, thus carries out axial location to separation sleeve 104.In certain embodiments, separation sleeve 104 can be formed through but not limited to the technique such as pultrusion, mold pressing.
