|
摘要
为了研究两种型钢混凝土剪力墙(内置型钢框架的混凝土剪力墙和内置型钢桁架的混凝土剪力墙)在受弯情况下的正截面受力状态,以这两种型钢混凝土中高剪力墙和普通钢筋混凝土中高剪力墙在无轴力作用下的单调和反复水平加载试验为基础,通过力学分析和参考现有规范,主要考虑型钢组件对墙体受弯性能的影响,提出了此两种型钢混凝土中高剪力墙在受弯状态下正截面开裂荷载和极限荷载的计算方法,进一步提出了简化计算方法,并将计算结果与试验结果进行比较验证,为此种构件的工程设计提供算法。
To clarify the right cross section bending mechanics about two kinds of steel reinforced concrete(SRC) shear wall(reinforced concrete shear wall embedded with steel shape frame and reinforced concrete shear wall embedded with steel shape truss),based on the tests of the two kinds of SRC mid-rise shear wall and common steel reinforced concrete shear wall under monotonic and cyclic lateral load without the axial load,referring to the current codes and theoretical analysis,mainly considering the effect of the embedded shape steel frame or truss on the shear wall's right cross section bending mechanics,this paper provided the theoretical calculation methods for the right cross section bending cracking load and ultimate load for these two kinds of SRC shear wall under lateral load,and the simplified practical calculation methods as well,then compared calculation results with the test results,so that got the practical design methods for the real project.
