摘要:
为了研究冷弯薄壁型钢住宅结构平面质量中心、楼层形心与刚度中心偏差较大时,结构整体扭转效应的不利影响,将楼层平面内水平荷载(风、地震)作用下结构位移分解为平动和转动2种状态,得到相应状态下各组合墙体所承担的剪力,然后将其效应进行叠加,推导出了结构的线弹性层间扭转角及组合墙体剪力和侧移变形计算公式。对某冷弯薄壁型钢多层住宅结构在水平荷载作用下的层间扭转效应进行了简化计算,并运用ANSYS进行了数值模拟分析。结果表明:水平扭转效应对该类结构影响显著,简化计算公式和有限元程序数值模拟所得结果具有较好的一致性,简化计算公式可供实际工程中对该类结构整体扭转效应的计算分析时参考。
Abstract:
In order to study the disadvantageous influence of torsional effect of cold-formed thin-walled steel structure, whose deflections among the structural stiffness center, mass center and geometry center existed, the structural total displacements were divided into parallel displacement and rotational displacement, and the parallel shear and the rotational shear of composite walls were accordingly obtained, then the effect would be superposed. Finally, the calculation formulae of the structural linear-elasticity storey torsion angle, shear force and lateral displacement of composite walls were derived. The storey torsional effect of cold-formed thin-walled steel residence structure under horizontal load was calculated by the simplified formula, and the numerical result was analyzed by ANSYS finite element program. Results show that the calculated results using two methods are close to each other, and the structure response by torsional effect under horizontal load is distinct. The simplified formula can be used as reference on calculation of torsional effect of cold-formed thin-walled steel residence structure in engineering.
