组合式密肋复合墙体的受力性能研究

ANALYSES OF MECHANICAL BEHAVIORS OF COMBINATIONAL MULTI-RIBBED COMPOSITE WALL

在课题组前期科研成果的基础上,通过1/2模型组合式密肋复合墙体在水平低周反复荷载作用下的试验研究,并与单片标准密肋复合墙体进行对比分析,研究了组合式墙体的主要破坏特征;探讨了墙体的强度,滞回特性,耗能性能及抗倒塌能力。最后给出了组合式墙体的刚度计算公式和斜截面抗剪承载力公式。试验及理论研究表明:提出的墙体抗剪承载力公式计算值与试验值吻合较好,适用于实际工程应用。

Based on the previous studies on the subject and by researching on the test of a 1/2-scaled combinational multiribbed composite wall under low-cyclic reversed horizontal load in contrast with a standard Wall, we are devoted to fulfilling the following points on the combinational wall in this paper： studying the main failure patterns; discussing the mechanical behaviors such as bearing capacity, hysteretic loop and so on, finally giving the formulas of rigidity and shear-bearing capacity. Experiment and theoretic research show： that the value of the shear-bearing capacity formula approximates to the experimental result, and can be applied to practical projects.
