加斜撑冷弯薄壁型钢组合墙体的抗震性能OACSCD
Seismic performance of diagonally braced cold-formed thin-walled steel composite walls
通过对竖向荷载作用下加斜撑冷弯薄壁型钢组合墙体的抗震性能试验研究,考察了墙体的受力特性、破坏模式和滞回性能,分析了覆面板对组合墙体滞回性能、延性和耗能能力的影响.结果表明:相同竖向荷载作用下,单面覆OSB板墙体较无面板墙体的抗剪承载力提高了38.79％;墙架柱轴压比为0.24较轴压比为0.16的单面覆OSB板组合墙体抗剪承载力提高了7.5％,屈服位移降低了8.1％,墙体延性系数μ提高了4.5％,耗能系数E提高了4.1％,加斜撑冷弯薄壁型钢组合墙体…查看全部>>
Through an experimental investigation of the seismic performance of diagonally braced cold-formed thin-walled steel composite walls subj ected to vertical loads,the mechanical properties,failure modes,and hysteresis properties of the walls were elucidated. In addition, the influence of a sheathing panel on the hysteresis performance,ductility,and energy dissipation of the composite walls was analyzed.The experimental results show that the shear bearing capac…查看全部>>
