蒙皮效应在建筑结构中的研究与应用进展

Research and application progress of diaphragm effect in building structure

对蒙皮效应的产生机理及条件进行了介绍,并基于前人的研究成果,从连接方式的性能、蒙皮体支撑构件的静力特性、蒙皮体的抗剪性能、蒙皮单元和主结构的协同工作性能及空间结构蒙皮效应5个方面对蒙皮效应在建筑结构中的研究与应用进行了梳理和总结。在前人研究成果的基础上提出,由于蒙皮的抗剪性能、板与构件之间的连接件数据不足,在目前的结构设计中没有考虑蒙皮效应的有利影响,有必要针对考虑蒙皮效应的设计方法开展进一步研究,提出更合理、简化的设计方法。

The generation mechanism and conditions of the diaphragm effect were introduced,based on the previous research results,the recent research on diaphragm effect from five aspects was summarized:the performance of the connection mode,the static characteristics of the diaphragm body support member,the shear performance of the diaphragm body,cooperative work performance of diaphragm unit and main structure and diaphragm effect of spatial structure.On the basis of previous research results,it was proposed that due to insufficient data on the shear resistance of the diaphragm and the connection between the plate and the member,the beneficial influence of the diaphragm effect is not considered in the current structural design.Therefore,it is necessary to conduct further research on the design method considering diaphragm effect and put forward a more reasonable and simplified design method.
