摘要

背栓节点拉拔性能是影响石材面板平面外承载能力的主要因素。本文在考虑不同材料性能参数和初始状态下,提出了石材面板背栓节点拉拔作用下的三种力学模型及相应破坏模式;对三种模型的关键参数和力学行为进行探讨;完成了石材面板背栓节点拉拔试验,验证了所提出的力学模型及破坏模式的合理性。

Abstract

The pull-out performance of backbolt joints is the main factor affecting the out-of-plane strength of stone panels. In this paper, with considering different material properties and initial states,three mechanical modes and failure models of stone panel backbolt joints under pull-out actions are proposed, the key parameters and mechanical behavior of the three models are discussed, the pull-out tests of stone panel backbolt are carried out, and the applicability of the proposed mechanical modes and failure models are verified.
