摘要
通过有限元建模分析,研究了拉索直径对预应力巨型支撑-钢框架结构抗侧移性能的影响;着重研究了拉索直径、预拉力和最大层间位移这几个参量之间的相互关系,并推导了最大层间位移关于拉索直径的拟合公式。经算例验证,该公式具有较好的适用性和精度。文章的相关研究结论可为预应力巨型支撑-钢框架结构拉索直径的优化提供参考依据。
Based on the nonlinear finite element software, influence of cable diameter on lateral performance of prestress-mega-braced steel frame structure is researched; the relations among cable diameter and prestress and most story drift are studied emphatically, fitting formula of most story drift on cable diameter is derived. The result indicates that this formula has a good applicability and precision by numerical examples. It provides references for optimizing diameters of prestress-mega-braced steel frame structures.
