Description
Technical field
The present invention relates to a kind of shearing-type eccentrically braces structure of thermal power plant bunker bay.
Background technology
Shearing-type eccentrically braces structure takes into account the strength and stiffness and pure steel frame inelastic behaviour of center support frame
And energy dissipation it is strong the advantages of.Active beam link is the weak spot in shearing-type eccentric structure, in rarely occurred earthquake, is initially entered in the wrong
State is taken, shear plasticity hinge is formed, by the plastic deformation dissipation seismic energy of active beam link, plays the role of " fuse ",
So as to protect other components in addition to active beam link without prejudice, ensure that shearing-type eccentrically braces structure is safe and reliable, ensure
The life security of personnel.
In order to realize under rarely occurred earthquake effect, active beam link initially enters the target of shear yielding state, it is necessary to ensures
The length of active beam link in shearing-type eccentrically braces structure meets following require：
e≤1.6MS/VS
E-active beam link length,
MSThe overall plastic property bend-carrying capacity of-active beam link,
VSThe overall plastic property shear resistance capacity of-active beam link.
According to the above-mentioned length requirement to active beam link, inventor is to the active beam link e's of the bunker bay in thermal power plant
Length limit is counted, its length is usually no more than 3m.
The supporting structure of existing thermal power plant bunker bay can be with as shown in Figure 1, including the first frame column 1 and first
Supporting beam 3 that corresponding second frame column 2 of frame column 1, both ends are fixedly connected with the first frame column 1 and the second frame column 2 respectively,
One end is fixed on the first frame column 1, and the other end is fixed on the support 4 in supporting beam, wherein in supporting beam 3 with support 4 and the
It is provided with the part l of two frame columns 2 connection for crane the first track 601 and the second track 602 for coal-grinding machine overhauling,
Since crane with the distance of the first track 601 and the second track 602 in C-D directions is usually 7 meters or so, in supporting beam 3
The part l being connected with 4 and second frame column 2 of support is more than 7 meters, the knot of existing thermal power plant bunker bay as shown in Figure 1
The part l being connected in supporting beam 3 in structure with 4 and second frame column 2 of support is unsatisfactory for shearing-type eccentrically braces structure to energy consumption
The limit value requirement of beam section length e, that is to say, that the structure of existing thermal power plant bunker bay as shown in Figure 1 is non-shear
Type eccentrically braces structure, so its anti seismic efficiency does not have the anti seismic efficiency of shearing-type eccentrically braces structure good.
