摘要：以轻钢龙骨和钢板网为骨架，石膏基聚苯颗粒砂浆为填充材料制备两种构造形式的新型复合墙板，并对其抗弯承载性能、隔声性能和耐火性能进行了研究。结果表明：石膏基聚苯颗粒砂浆的干密度、导热系数和抗压强度均随着聚苯颗粒掺量的增加而降低，且聚苯颗粒的最佳掺量为0.8%；两种构造形式复合墙板的破坏荷载与自重荷载的比值达到7.0以上；两种构造形式复合墙板的空气声计权隔声量达40 dB以上，耐火极限可达2 h。 Abstract: Two kinds of new composite wall panels were prepared with light steel keel and expanded metal mesh as the skeleton and gypsum-based polystyrene particle mortar as the filling material, and their flexural bearing performance, sound insulation performance and fire resistance performance were studied. The results show that the dry density, thermal conductivity and compressive strength of gypsum-based polystyrene particle mortar decrease with the increase of polystyrene particle content, and the optimum content of polystyrene particle is 0.8%. The ratio of the failure load to the self-weight load of the composite wall panels of the two structural forms is above 7.0. The air acoustic meter weight sound insulation of the composite wall panels of the two structural forms is more than 40 dB, and the fire resistance limit can reach 2 hours.

摘要：为了验证多腔式双钢板组合剪力墙的抗震优越性，制作了钢筋混凝土剪力墙和多腔式双钢板组合剪力墙，通过低周反复水平荷载试验，获得了两种剪力墙的破坏形态、滞回曲线和骨架曲线；建立了ABAQUS有限元模型，进行了多腔式双钢板组合剪力墙的抗震试验仿真分析，模拟了其破坏形态和累计损伤状态。结果表明：多腔式双钢板组合剪力墙具有承载力大、延性好、耗能强等优点；构件最终破坏时，虽然管内混凝土受压塑性变形发展较大，导致外侧双钢板明显臌胀，但管内混凝土并没有压碎，可以继续工作承担荷载；构件的最终破坏形态为受拉钢板撕裂破坏，属于延性破坏。 Abstract: In order to verify the seismic superiority of multi cavity double steel plate composite shear wall, a reinforced concrete shear wall and multi cavity double steel plate composite shear wall were made, and the failure modes, hysteresis curves and skeleton curves of two shear walls were obtained through low cycle repeated horizontal load tests. The ABAQUS finite element model was established to simulate the seismic test of multi cavity double steel plate composite shear wall, and its failure mode and cumulative damage state were simulated. The results show that the multi cavity double steel plate composite shear wall has the advantages of large bearing capacity, good ductility and strong energy consumption. When the component is finally damaged, although the compressive plastic deformation of the concrete in the pipe develops greatly and leads to the obvious heave of the outer double steel plate, the concrete in the pipe is not crushed and can continue to work and bear the load. The final failure form of the component is the tearing failure of the tensile steel plate, which is a ductile failure.
