Summary

One of the new building systems that is common in the world today is 3D concrete panels. One of the key questions about these panels is their performance and behavior under reciprocating side loads. In this study, the capacity and behavior of 3D panel walls were compared by comparing the behavior of these walls with similar shear walls under reciprocating lateral loads. In similar shear walls, the two concrete layers are integrated and the shears are removed. The aforementioned studies were performed by nonlinear static analysis of selected samples in ABAQUS software. The results show that as the sample height increases, the ratio of the capacity of the 3D panels to similar shear walls tends to be constant. The results of this study provide the opportunity to analyze and design similar shear walls instead of analyzing and designing more sophisticated 3D panel instruments.

1. Introduction

 

One of the fundamental questions about 3D panels is the shear capacity of these walls and their performance and behavior under reciprocating lateral loads. A 3D panel of mesh layers, joined by a number of diagonal cutters, creates instruments similar to a Space Frame. The space between the two layers of mesh is filled with polystyrene. Also, the mesh layers are shotcrete after installing the panel in place. As can be seen, the main difference between a 3D panel and a shear wall is its bilayer and the elements called shear that connect the two layers. This is what can affect wall behavior under lateral loads.

The published guidelines and guidelines have so far suggested the performance and capacity of a 3D wall under side loads similar to that of a shear wall. But here's the question of how far the two can be treated equally, and how reliable this replacement basically is. The main purpose of this study is to investigate the capacity and behavior of 3D panels under reciprocating lateral loads. This study compares the behavior of these walls with similar shear walls. In similar shear walls, the two concrete layers are integrated and the shears are removed.

The results of this study provide the opportunity to analyze and design similar shear walls instead of analyzing and designing more sophisticated 3D panel instruments.
