装配式混凝土剪力墙的各层剪力墙板通过柔性连接形成整体，在水平荷载作用下，其受力机制与现浇剪力墙明显不同。基于已有试验成果，采用多条连续直线逼近装配式混凝土剪力墙的非线性水平受力全过程，建立了相应的多线性简化分析模型。将多线性简化分析模型的计算结果与已有试验结果对比，验证了其准确性。多线性简化分析模型可较准确反映装配式混凝土剪力墙的抗侧性能，计算过程简单，可作为新型装配式混凝土剪力墙的分析与设计模型，并可用来评价其水平受力性能。

New precast concrete shear wall( NPC wall) has a pliability connection relative to the connected adjacent precast concrete panels. Thus, it has a force mechanism rather different from that of the monolithic cast?in?situ reinforced concrete wall under lateral force. A simplified model is produced for analysis and design with multiple straight lines approximating the nonlinear lateral resistance behavior of NPC wall. The applicability of multi?linear simplified model ( MLSM ) is validated by comparing the calculated results with available experimental results. The prediction results from MLSM using design parameters of material properties have also been presented, and there is adequate margin between prediction results and experimental results. MLSM has essentially reflected the lateral resistance mechanics and the calculation process is simple. It is recommended MLSM be suitable for the preliminary design and lateral resistance performance estimation of NPC wall.
