| 中文摘要 | 为研究钢-混凝土高层混合结构在大震下的抗震性能,对某实际型钢-混凝土高层建筑进行了动力弹塑性分析。运用三维有限元分析程序CANNY06,得出了结构在大震下的内力和变形规律,并与静力弹塑性分析结果进行对比。研究推覆分析是否适用于评价混合结构的抗震性能。研究钢-混凝土组合楼盖在大震下的工作性。结果表明:静力推覆分析不一定能满足“大震不倒”的抗震设防要求;当结构高宽比大于3时,组合楼盖在弹塑性阶段仍可按刚性楼盖考虑,而且高宽比越大,简化带来的误差越小。; The seismic behavior of a tall steel reinforced concrete(SRC) structure was analyzed using dynamic elastoplastic analysis.The CANNY06(a 3-D nonlinear static and dynamic structural analysis program) was used.The internal forces and deformations,including shear forces,overturning moments,lateral displacements,and drifts,were compared with those of a static elastoplastic analysis to evaluate the effectiveness of the pushover analysis.The behavior of the composite floor slab during the earthquake was also analyzed.The results show that the pushover analysis can not accurately predict whether a structure will resist major earthquake ground motions without collapse,and the rigid floor slab assumption for the composite floor slab is suitable for the structure height-width ratio greater than 3 with larger height-width ratios resulting in smaller errors.; 国家自然科学基金资助项目(50438020) |
