摘　　要：装配式复合模壳剪力墙体系是近年来快速发展的一项新技术,可在剪力墙、梁、柱等构件中应用。以实际项目为例,采用三种不同的建模方法,研究模壳剪力墙体系与现浇剪力墙在结构刚度、基底剪力、构件内力等方面的差异,并对模壳剪力墙体系进行大震弹塑性损伤分析。研究结果表明,模壳剪力墙体系的结构性能稍优于现浇剪力墙体系,安全冗余度较好。同时,通过对钢筋混凝土材料自重及周期折减系数等参数的调整,提出合理、可行的模壳剪力墙体系设计方法,为类似项目提供参考。The shear wall with prefabricated composite shell-form system is a new technology developed rapidly in recent years,which can be used in shear walls,beams,columns and other components.Taking the actual project as an example,three different modeling methods were used to study the differences between the shear wall with shell-form system and the cast-in-place shear wall in terms of structural stiffness,base shear force and component internal force,and the elastic-plastic damage analysis of the shear wall with shell-form system under large earthquakes was carried out.The results shows that the structural performance of the shear wall with shell-form system is slightly better than that of the cast-in-place shear wall system,and the safety redundancy is better.At the same time,through the adjustment of parameters such as the weight of reinforced concrete materials and the period reduction coefficient,a reasonable and feasible design method of the shear wall with shell-form system was proposed,which provides a reference for similar projects.
