Eccentric supporting structure energy dissipation beam and supporting structure component
The embodiment of the invention provides an eccentric supporting structure energy dissipation beam and a supporting structure component, and the eccentric supporting structure energy dissipation beam comprises a first beam section, a second beam section and a third beam section which are sequentially connected in the first direction. When the energy dissipation beam web of the second beam section generates shear plastic deformation strengthening and the shear bearing capacity reaches mu times of full-plastic shear bearing capacity, the first beam section and the third beam section reach full-plastic flexural bearing capacity, and mu is a constant ranging from 1.1 to 1.25. When the eccentric supporting structure energy dissipation beam is in an earthquake, the energy dissipation beam web of the second beam section is subjected to shear yield plastic deformation firstly, and then the energy dissipation beam first flanges and the energy dissipation beam second flanges of the first beam section and the third beam section are subjected to plastic deformation. Therefore, the eccentric supporting structure energy dissipation beam has better anti-seismic performance.
本发明的实施例提供了一种偏心支撑结构耗能梁和支撑结构构件，所述偏心支撑结构耗能梁包括沿第一方向顺序连接的第一梁段、第二梁段和第三梁段，在第二梁段的耗能梁腹板产生剪切塑性变形强化且受剪承载力达到μ倍全塑性受剪承载力时，第一梁段和第三梁段达到全塑性受弯承载力，μ为取值范围为1.1～1.25的常数。以使本发明实施例的偏心支撑结构耗能梁在地震时，第二梁段的耗能梁腹板先发生剪切屈服塑性变形，第一梁段和第三梁段的耗能梁第一翼缘和耗能梁第二翼缘后发生塑性变形。因此，本发明实施例的偏心支撑结构耗能梁具有更好的抗震性能。
