摘要：结合开发的自动化成组立模设备，研究并优化了快速组模、预埋件定位、模板变形和漏浆控制、浇筑振捣和自动养护等关键工艺环节，解决了预制混凝土内墙板立模生产的技术难题。通过工程应用，说明了立模生产的内墙板相比平模在质量上有明显提升。采用立模除了可节省空间外，生产效率大大提高，能耗明显降低，社会和经济效益显著。 Abstract: In combination with the developed automatic group vertical mold equipment, the key technologies such as rapid mold forming, embedded part positioning, formwork deformation and slurry leakage control, casting and vibration,automatic curing are studied and optimized, and the technical difficulties in precast concrete inner wall panel manufacturing technique by using the vertical mold are solved. Through the engineering application, it is shown that the quality of the inner wall panel produced by the vertical mold is significantly improved compared with that of the flat mold.In addition to greatly saving space, the use of the vertical mold greatly improves production efficiency, significantly reduces energy consumption, and has significant social and economic benefits.

摘要：基于ABAQUS有限元模拟分析软件对不同厚度与尺寸的18组板型不锈钢拉结件进行了模拟，通过数值计算分析的方法确定了其抗剪承载力，得出了板型拉结件应力发展过程。结果表明：板型不锈钢拉结件具有较大的平面内抗剪承载能力，当拉结件尺寸相同时，其抗剪承载力随厚度的增加而增大；同厚度、同高度的不锈钢拉结件的长度越大，抗剪承载力越大；同厚度、同长度的不锈钢拉结件，随着高度的增加，其抗剪承载力变化不大；设计中可以屈服强度为基准，安全系数取3.0，确定板型不锈钢拉结件的允许剪切强度。 Abstract: Based on ABAQUS finite element simulation software, 18 groups of stainless steel tie-in pieces with different thickness and size were simulated, and their shear capacity was determined by numerical calculation and analysis, and the stress development process of the plate type stainless steel tie-in parts was obtained. The results show that the plate type stainless steel tie-in parts have large in-plane shear bearing capacity. When the size of the tie-in parts is the same, the shear bearing capacity increases with the increase of the thickness. The longer the stainless steel tie-in pieces of the same thickness and height, the greater the shear bearing capacity. When the thickness and length of stainless steel pull-out pieces are the same, the shear bearing capacity has little change with the increase of height. The yield strength can be taken as the basis in the design, and the safety factor is taken as 3.0 to determine the allowable shear strength of plate type stainless steel tie-in parts.

摘要：通过选取典型的足尺试验模型，从其骨架曲线、荷载及位移等方面进行了ABAQUS验证，从而得出有限元计算的可靠性。基于此，进行了高轴压比（0.5、0.7、0.9）下十字型ECC框架节点在循环荷载下的抗震性能分析。结果表明：设计轴压比为0.9时框架节点易出现严重的节点核心区剪切破坏，耗能相比于0.5轴压比下降了约11.2%，出现严重的塑性变形；0.5轴压比下位移延性系数μ达到了5.37，所有试件μ均值达到了3.0以上，破坏模型均为延性破坏。 Abstract: The typical full-scale test models were selected and verified by ABAQUS software from the aspects of skeleton curve, load and displacement, so as to obtain the reliability of the finite element method. Based on this, the seismic behavior of ECC frame joints with high axial compression ratio (0.5, 0.7, 0.9) under cyclic load was analyzed. The results show that when the design axial compression ratio is 0.9, the frame joints are prone to serious shear failure in the core area, and the energy consumption is about 11.2% lower than that of the 0.5 axial compression ratio, which leads to serious plastic deformation. When the design axial compression ratio is 0.5, μ reaches 5.37, and the average μ of all specimens reaches above 3.0, and the failure mode is ductile failure.

摘要：采用碳化深度测量、SEM、XRD等手段，在特定的环境下研究了不同等级砂加气混凝土的碳化性能和力学性能。结果表明：由于砂加气混凝土水化生成的托贝莫来石逐渐转变为方解石，砂加气混凝土的抗压强度随着碳化深度的增加而明显下降。 Abstract: The carbonation performance and mechanical properties of different grades of sand aerated concrete were studied under specific conditions by means of depth measurement, SEM and XRD. The results show that the compressive strength of sand aerated concrete decreases obviously with the increase of carbonation depth because of the tobermorite formed by hydration of sand aerated concrete gradually transforms into calcite.
