Below, the structure of the present embodiment structural behavior with steel 100 is described.Fig. 5 is the table of the structure of expression present embodiment with the characteristic of the shaped steel of steel 100 and prior art.

Here, the shaped steel that compares as prior art be that patent documentation is 4 disclosed, a plurality of being set up in parallel and form the box steel 10 of deck construction.The contrast box steel 10 width and highly all be 200mm, wall thickness 4.5mm.And the structure shown in (b) hurdle of Fig. 5 of present embodiment has with steel 100 and is of a size of: the height of web 102 is 200mm, last flange of beam 104 and down the length of flange of beam 106 be 200mm, wall thickness is 4.5mm.And the structure shown in (c) hurdle of Fig. 5 of present embodiment has with steel 100 and is of a size of: the height of web 102 is 200mm, last flange of beam 104 and down the length of flange of beam 106 be 295.5mm, wall thickness is 4.5mm.

Structure shown in (b) hurdle of Fig. 5 of present embodiment with steel 100 is, makes web 102, goes up flange of beam 104 and the width of length and the box steel 10 of contrast of flange of beam 106 and highly identical down.At this moment, the structure of present embodiment is compared with box steel 10 with steel 100, and sectional area A is roughly 3/4, and the steel material of use reduces.On the other hand, the bending stiffness of per unit area (second moment of area I) I/A is 1.169 times of bending stiffness (second moment of area I) I/A of the per unit area of box steel 10.

And, structure shown in (c) hurdle of Fig. 5 of present embodiment with steel 100 is, make the length of web 102 identical with the height of box steel 10, and the length to last flange of beam 104 and following flange of beam 106 is set, so that structure is identical with the sectional area of box steel 10 with the sectional area of steel 100.At this moment, because both sectional area is identical, so the steel material that uses equates that but the bending stiffness of per unit area (second moment of area I) I/A is 1.267 times of bending stiffness (second moment of area I) I/A of the per unit area of box steel 10.

As mentioned above,, dispose a plurality of structures and compare with the deck construction of the existing box steel 10 of configuration, can make the structural behavior raising and obtain more light-weighted structure with the deck construction of steel 100 according to present embodiment.

Below, with reference to Fig. 6 to the last flange of beam 104 of present embodiment and down the width L of the best of flange of beam 106 describe.Fig. 6 is that the structure of expression present embodiment is with the related structural behavior of the bending stiffness of steel 100 and the chart of the relation between flange of beam width/web height.

The scope of flange of beam width L is the generation, economy of the amount of deflection of having considered flange of beam, partial buckling and definite.That is, flange of beam width large economy more is high more, but when the generation of the amount of deflection that is concerned about flange of beam, partial buckling, determines preferred maximum, minimum value, the preferred maximum value of flange of beam width.

At first, the preferred maximum to flange of beam width L describes.When making flange of beam width L become big, can reduce the structure that disposes in order the to form deck construction quantity of steel 100, also can reduce the sum of web, but flange of beam width L is when excessive, structure becomes problem with the amount of deflection δ (shown in Figure 1B) of the last flange of beam 104 of steel 100.

The thickness of slab of flange of beam 104 is t, uniformly distributed load w=2900N/m on establishing ²Act on the flange of beam 104 and (implement the stow loading of the office that makes 85 based on building standard method), and to make structure be that L/300 is when following with the maximum defluxion δ max of steel 100, by following calculating, the maximum value of flange of beam width L can be expressed as the function of the t of following formula 4 expressions.

δ＝5wL ⁴/(384EI)≦L/300···(1)

Here, E is a tensile modulus of elasticity.And, because w=2900N/m ²If therefore establishing the load width is 1m, and carries out unit transformation, then becomes

w＝2.9N/mm···(2)

For second moment of area I, be 1000mm if also establish load width b, then become

I＝bt ³/12＝1000t ³/12···(3)

With above-mentioned formula (2), (3) substitution formula (1), and establish E=205000N/mm ², then become

L/t≦115···(4)

Therefore, the preferred maximum of flange of beam width L is 115t, is 115 times of thickness of slab t of flange of beam 104.

Yet, in aforementioned calculation, calculated the maximum value of flange of beam width L according to structure with the amount of deflection of steel 100, but supposition has acted on the situation of bigger out-of-plane bending power on the floor of deck construction, just need estimate the partial buckling intensity of last flange of beam 104.

Therefore, if just can estimate with the similar structure of sheet material, thus can quote the following formula (5) of buckling and taking place that is used to suppress sheet material, and calculate the maximum value of flange of beam width L.

$L/t\≤740/\sqrt{f}\·\·\·\left(5\right)$

Here, f be act on flange of beam 104, be the active force of vertical direction with respect to 104 of last flange of beams, be and considered 3 times to the design basis intensity F of general steel SS400 value 235N/mm ²The value of safety coefficient.Therefore, if, then become with f substitution formula (5)

Therefore, the preferred value of flange of beam width L is below the 84t, is below 84 times of thickness of slab t of flange of beam 104.In addition, by rib is set, can more suitably determine flange of beam width L (for example more elongation) on flange of beam.Here, so-called rib is the rib that effectively prevents amount of deflection and/or partial buckling, for example is, can make in the amount of deflection that produces on the flange of beam is below the L/300, has the rib of the structure of the generation that can suppress partial buckling.

Below, the minimum value of flange of beam width L is described.When flange of beam width L shortens, be not easy to produce the problem of rigidity (amount of deflection), intensity (partial buckling), so will considering economy, the preferred minimum value of flange of beam width L determines.

That is, structure is decided by the relation with the bending stiffness (I/A) of per unit area with the economy of steel 100.When to the structure of present embodiment with the bending stiffness (I/A) of the per unit area of steel 100, and flange of beam width when representing with respect to the relation between the ratio of web height, become chart shown in Figure 6.When to the I/A of the present embodiment shown in (c) hurdle of (b) hurdle of Fig. 5 and Fig. 5, when drawing with respect to the data of the ratio of web height, become 2 points shown in Figure 6 with the flange of beam width.And the I/A of the box steel 10 that uses as prior art is 6374mm ², be the value shown in the dotted line in Fig. 6.Structure is preferably the above value of I/A of box steel 10 with steel 100.Therefore, according to chart shown in Figure 6, the preferred minimum value of flange of beam width L is 1/2 of a web height.

As mentioned above, the scope of flange of beam width L is preferably, and more than 1/2 of web height, goes up below 163 times of thickness of slab of flange of beam 104, more preferably goes up below 84 times of thickness of slab of flange of beam 104.

According to the 1st embodiment of the present invention, the structure formation deck construction that has web 102, goes up flange of beam 104 and following flange of beam 106 in abutting connection with configuration abreast with steel 100, can constituent ratio dispose the more light-weighted deck construction of deck construction of the box steel 10 that uses as prior art thus, and can further improve structural behavior.And because can be stacked a plurality of structures are with steel 100, so do not take the place when transportation, the result can improve the conevying efficiency of steel.
