摘要：针对传统装配式隔墙安装工艺存在施工效率低、安装质量差等缺点，以蒸压轻质加气混凝土墙板施工为背景，提出了一种新型装配式隔墙连接节点构造形式，并介绍了其生产工艺、安装流程和施工控制要点，可为装配式隔墙的快速安装提供参考。 Abstract: Aimed at the shortcomings of low construction efficiency and poor installation quality in traditional prefabricated partition wall installation technology, a new type of prefabricated partition wall connection node is proposed based on the construction of autoclaved lightweight aerated concrete wall panels. Its production process, installation process, and construction control points are introduced, which can provide a reference for the rapid installation of prefabricated partitions walls.

摘要：为了研究高温对蒸压加气混凝土（AAC）物理力学特性的影响，对不同温度作用后的AAC试件进行了质量损失、纵波波速、单轴抗压强度等性能试验，并结合XRD及SEM测试，分析了温度对AAC成分与微观结构的影响。结果表明：随着温度的增加，高温后AAC试件表面颜色逐渐加深，质量损失不断增加；当温度低于100 ℃时，AAC试件的纵波波速略有增加，当温度高于100 ℃时不断下降；常温至300 ℃作用下，AAC试件的单轴抗压强度不断增大，超过300 ℃后逐渐下降；温度为900 ℃时，AAC试件碎裂，并失去了承载能力；随着温度的增加，AAC的物相成分和微观结构都发生不同程度的变化，由此导致AAC宏观物理力学特性发生相应变化。 Abstract: In order to study the influence of high temperature on the physical and mechanical properties of autoclaved aerated concrete(AAC), the physical and mechanical properties of AAC specimens treated with different temperatures such as mass loss, wave velocity and uniaxial compressive strength were tested. XRD and SEM were used to explore the effects of temperature on the composition and microstructure of AAC. The results show that the surface color of AAC specimens gradually deepens and the mass loss grows with the increase of temperature. The wave velocity increases slightly at the 100 ℃, and decreases continuously when the temperature is above 100 ℃. The uniaxial compressive strength of AAC specimen keeps increasing from room temperature to 300 ℃, and decreases when it exceeds 300 ℃. When the temperature reaches 900 ℃, the AAC specimens crack and lose the bearing capacity. With the increase of temperature, the phase composition and microstructure of AAC change to varying degrees, which leads to the corresponding changes in the macroscopic physical and mechanical properties of AAC.

摘要：通过给暗柱配置预应力钢绞线，墙身配置普通钢筋的复合配筋方式设计了3面复合配筋预应力钢绞线剪力墙，并设计了1面普通钢筋混凝土剪力墙进行对比。基于Diana有限元分析软件对两种墙体进行了拟静力分析，对比研究了暗柱不同配筋形式及轴压比对剪力墙滞回性能、承载性能、变形性能、刚度退化、耗能能力及裂缝开展的影响。结果表明：与普通钢筋混凝土剪力墙相比，复合配筋预应力钢绞线剪力墙可以有效地提高构件的承载性能，并抑制裂缝的开展；随着轴压比的增大，构件承载力有所提升，但延性显著下降。 Abstract：Three composite reinforcement prestressed strand shear walls and one ordinary reinforced concrete shear wall were designed by the composite reinforcement method of the concealed column configuration prestressed strand and ordinary reinforcement in the wall. Based on Diana finite element analysis software, the simulations of the two types of walls were carried out in a quasi-static test, and the effects of different reinforcement forms and axial compression ratios of the concealed columns on the hysteresis performance, load-bearing performance, deformation performance, stiffness degradation, energy dissipation capacity and crack development of the shear walls were comparatively studied. The results show that the composite reinforced prestressed stranded concrete shear walls can effectively improve the load bearing performance and inhibit the crack development compared with the ordinary reinforced concrete shear walls. With the increase of axial compression ratio, the load capacity of the member is increased, but the ductility of the member is significantly decreased.
