摘要
针对用于代替黏土砖住宅结构的新型"人"字支撑复合结构进行了空间建模分析及其空间结构静力性能分析.通过建模分析,提出了空间楼板单向传力的建模方法,解决了有限元软件无法模拟单向板的问题.然后计算了新型复合结构在六种静力荷载组合工况作用下的内力和位移,结果表明,空间复合结构在各种荷载组合工况下,其梁的最大挠度小于规范值,顶点最大水平位移及最大层间位移均小于框-剪结构的规范限值;梁、柱、支撑仅需要构造配筋,其受力主要考虑"恒载+满跨活载"及"恒载+0.9(风载+满跨活载)"组合工况.因此空间复合结构具有良好的刚度和受力性能.
The spatial modeling and the spatial static overall performance of the new "∧" brace compound structure which would be used to substitute clay brick residential structure are mainly studied.Through modeling analysis,the modeling method that the spatial plate transferred load in one-way is put forward.The problem that the ANSYS software has not one-way plate is solved.Based on the calculation of the new compound structure under the six kinds of loads combinations,the result show that the biggest deflection of beam is smaller than the standard value under each kind of load and the vertex maximum horizontal displacement and the biggest story displacement are also smaller than that of the frame-shearing force wall structure.The beam,column and brace are requested to satisfy detail reinforcements.In addition,the static performance of the new compound structure is mainly considered under "the dead load and completely cross live load" and "the dead load and 0.9(wind load and completely cross live load)".Therefore,the spatial compound structure has the good stiffness and force performance.
