摘要

基于结构应力状态的概念，提出了一种预测均布横向荷载作用下砌体墙板破坏荷载的方法。首先，通过试验研究了砌体墙板在均布横向荷载作用下的结构应力状态特征。然后，提出了一个新的参数来表征结构的应力状态。接下来，使用所提出的参数建立了指定基础墙板和其他墙板之间的破坏载荷关系。建立了一种基于结构应力状态参数的砌体墙板破坏荷载预测方法（称为应力状态法）。以下案例研究通过将预测的失效载荷与实验结果以及现有屈服线理论（YLT）、有限元分析方法和基于GSED的细胞自动机（CA）方法预测的结果进行比较，验证了ST方法。ST方法为基于结构应力状态的结构分析提供了一种创新的方法。

A method for predicting failure load of masonry wall panel based on structural stress state

This paper proposed a method for predicting the failure loads of masonry wall panels subject to uniformly distributed lateral loading based on a concept of structural stress state. Firstly, the characteristics of the structural stress state of masonry wall panels subjected to uniform distributed lateral loading were investigated through experimental results. Then, a new parameter was proposed to characterize the structural stress state. Next, the relation of the failure loads between a specified base wall panels and other wall panel was established using the proposed parameter. In this way, a method (called as stress state (ST) method) based on structural stress state parameter to predict the failure load of masonry wall panel from the base wall panel was established. The following case studies validated the ST method by comparing the predicted failure load with experimental results as well as those predicted from the existing yield line theory(YLT), the FEA method and the GSED-based cellular automata (CA) method. The ST method provided an innovative way of structural analysis on the basis of structural stress state.

期刊介绍： Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
