摘要

节能型砌块与隐形多肋框架组合墙是一种新型承重墙。本文主要研究了其在水平循环荷载作用下的滞回规律。首先,基于12个试件在水平循环荷载作用下的试验数据,分析了轴压比和剪跨比两个重要参数对恢复力模型的影响。其次,通过理论分析和实验数据回归分析相结合,建立了考虑四个特征点和卸载刚度退化规律的四线性恢复力模型,推导了EBIMFCW峰值载荷的理论公式;最后,通过分析典型滞回线的滞回特性,确定了恢复力模型的滞回路径。结果表明,本文所建立的四线性恢复力模型计算曲线与试验曲线吻合较好,特别是墙体峰值荷载计算值与试验值非常接近,可为EBIMFCW的弹塑性分析提供参考。

Analysis of hysteresis rule of energy-saving block and invisible multi-ribbed frame composite wall
The energy-saving block and invisible multi-ribbed frame composite wall (EBIMFCW) is a new type of load-bearing wall. The study of this paper focus on it is hysteresis rule under horizontal cyclic loading. Firstly, based on the experimental data of the twelve specimens under horizontal cyclic loading, the influence of two important parameters of axial compression ratio and shear-span ratio on the restoring force model was analyzed. Secondly, a tetra-linear restoring force model considering four feature points and the degradation law of unloading stiffness was established by combining theoretical analysis and regression analysis of experimental data, and the theoretical formula of the peak load of the EBIMFCW was derived. Finally, the hysteretic path of the restoring force model was determined by analyzing the hysteresis characteristics of the typical hysteresis loop. The results show that the curves calculated by the tetra-linear restoring force model in this paper agree well with the experimental curves, especially the calculated values of the peak load of the wall are very close to the experimental values, which can provide a reference for the elastic-plastic analysis of the EBIMFCW.
