内嵌ALC墙板-钢框架体系的滞回及抗裂性能研究
Study on Hysteretic Performance and Crack Resistance of Embedded ALC Wall Panel-Steel Frame System
摘要
Abstract
Autoclaved Lightweight Concrete(ALC)walls have become a commonly used wall form in prefabricated building structures,but wall cracking,which often occurs during normal use,adversely affects the aesthetics and durability of the building.In order to study the cracking resistance of embedded ALC wall panels and their effect on the stress performance of steel frames,this paper designs and completes the quasi-static full-scale tests of two single-story single-span rigidly-jointed steel frame specimens with embedded ALC walls which are connected to the steel frames with in-built anchors and pipe clips,respectively.Varying different wall finishes,the hysteresis curves,skeleton curves,stiffness degradation curves of the specimens are obtained from the actual measurements and the key experimental phenomena are observed.The test results show that the hysteretic curves of the two specimens are full hysteresis loops,the bearing capacity of the built-in anchor specimen is slightly higher than that of the pipe clip specimen,and the specimens have a good ability to work together.Considering the load capacity and stiffness,the lateral resistance of the built-in anchor specimen is better than that of the pipe clip specimen.The use of modified two-component MS adhesive as the connection material between ALC wall panels and steel frames results in later cracking compared to the use of polyurethane foam connection,which indicates that MS adhesive has a good deformation capacity,which helps to improve the cracking resistance of the wall.关键词
