多层装配整体式钢网格框架墙的试验研究

Experimental research on assembled monolithic steel grid frame wall

通过试验验证对比分析了装配整体式钢网格框架墙的滞回耗能能力,结果表明,该结构承重外墙在往复荷载作用下抗震性能优异、变形恢复能力好、延性好,承载能力较佳。梁端及柱端截面处的应变值、荷载-位移滞回曲线、骨架曲线与有限元分析的数值吻合情况较好,用于实际工程时,其梁柱构件可按整根构件建模。

Hysteretic energy dissipation capacity of assembled monolithic steel grid frame wall was mainly tested,compared and analyzed by experiment. Results proved that under cyclic loading the load-bearing external wails of such a new steel structure has a good carrying capacity,energy dissipation capacity,deformation recovery ability and good seismic performance. The strain val- ue at beam-end section and column-end section,the value of the hysteresis curve and the skeleton curve of whole specimens of the framework wall consisted with the finite element analysis well. When being used in actual engineering, the beam and column members can be modeled as a whole member.
