摘要
外壳预制式混凝土结构是一种新型装配式结构形式,采用混凝土保护层与箍筋预制、核心区域混凝土现浇的施工方式.为研究外壳预制式装配桥墩的抗震性能,进行现浇桥墩和外壳预制式装配桥墩的有限元建模和拟静力试验数值模拟,对比分析现浇桥墩和外壳预制式装配桥墩的滞回曲线、骨架曲线等抗震性能指标.结果表明,外壳预制式装配桥墩与现浇桥墩抗震性能相近.
Abstract
The shell prefabricated concrete structure is a new type of prefabricated structure.The concrete cover and stirrups are prefab-ricated,and the concrete in the core area is cast in place.In order to study the seismic performance of the prefabricated shell piers,the finite element modeling and quasi-static test numerical simulation of the cast-in-place piers and the shell prefabricated piers were carried out,and the hysteresis curves,skeleton curve and other seismic performance indicators.The results show that the shell prefabri-cated piers have better integrity and have similar seismic performance to those of cast-in-place piers.
