【摘要】：积极研究和开发新型绿色环保建筑材料,推广绿色建筑墙体材料是我国住宅行业的发展趋势。绿色环保建筑材料石膏速成墙板在建筑结构中具有很多优势,最初是由澳大利亚设计生产的,近几年国内引进其相关技术并得到一定的发展。天津开发区福林发展有限公司开发生产了防水玻璃纤维石膏板和聚苯板保温材料一体的外保温石膏-聚苯复合板,在工厂里做成墙板成品,按设计要求裁制成符合要求的墙板,运送到施工现场并安装,带有空腔的石膏板作为现浇钢筋混凝土墙的两侧永久性免拆模板,形成具有外保温性能的新型复合混凝土-石膏墙板。此类型墙体是集承重、保温、隔热等于一体的新型环保建筑墙体,能够代替传统的承重剪力墙,具有很大的发展前景。目前对其结构性能的研究还处于初级研发阶段,为了弄清新型复合混凝土-石膏墙板的抗震性能,对其进行低周反复抗震性能试验研究和有限元数值分析具有重要的工程指导意义。本文是在天津开发区福林发展有限公司用新型复合混凝土-石膏墙板建成2栋3层住宅试验楼的基础上进行低周反复试验研究和数值模拟的。本试验研究工作所取得的研究成果和创新性主要表现在以下几个方面:1.重点设计了3块新型复合混凝土-石膏墙板L形节点试件,进行了固定轴压下低周反复荷载试验,摸清了L形试件在水平反复荷载作用下的破坏过程及形态、受力特点、变形能力等性能。2.通过试验记录的相关数据,分析研究了新型复合混凝土-石膏墙板L形试件在固定轴压和低周反复循环荷载作用下的开裂荷载、屈服荷载、屈服位移、极限荷载、极限位移等受力特性,并通过L形试件的延性、刚度退化、滞回性能、耗能性能研究了试件的节点抗震性能,得出了在此荷载作用下L形节点相对而言不易破坏,具有一定的安全性。3.利用大型通用有限元分析软件ABAQUS对新型复合混凝土-石膏板墙板L形试件进行了非线性有限元分析,并和低周反复试验结果进行了比较,二者基本吻合,为今后计算机模拟其它规格的新型复合混凝土-石膏墙板低周反复试验提供了参考。
[Abstract]:Actively researching and developing new green environmental protection building materials and popularizing green building wall materials are the development trend of our country's housing industry. Green environmental protection building material gypsum wall board has many advantages in the building structure. It was originally designed and produced by Australia. In recent years, the related technology has been introduced and developed in our country. Tianjin Development Zone Fulin Development Co., Ltd. has developed and produced an external insulation gypsum / polystyrene composite board with waterproof glass fiber plasterboard and polystyrene board insulation material, which is made into a wall board finished product in the factory and cut into a wall board according to the design requirements to meet the requirements. The gypsum board with cavity is used as the permanent non-detachable formwork on both sides of the cast-in-situ reinforced concrete wall to form a new type of composite concrete-gypsum wallboard with external thermal insulation. This type of wall is a new type of environmental protection building wall, which can take the place of the traditional load-bearing shear wall and has a great development prospect. At present, the research on the structure performance is still in the initial stage of research and development. In order to find out the seismic performance of the new composite concrete-gypsum wallboard, The experimental study of low cycle repeated seismic performance and finite element numerical analysis are of great significance in engineering. In this paper, the low cycle repeated test and numerical simulation are carried out on the basis of the construction of two three-story residential test buildings with a new type of composite concrete and gypsum wallboard in Fulin Development Company of Tianjin Development Zone. The research results and innovation of this experiment are mainly shown in the following aspects: 1. Three new composite concrete-gypsum wall L joint specimens were designed, and the low cycle repeated load tests under fixed axial compression were carried out, and the failure process, shape and stress characteristics of L shaped specimens under horizontal repeated load were found out. Deformability, etc. Based on the experimental data, the cracking load, yield displacement and ultimate load of the L-shaped composite concrete-gypsum wall slab under fixed axial compression and low cycle cyclic loading are analyzed and studied. The ultimate displacement and other mechanical properties, and through the ductility, stiffness degradation, hysteretic performance and energy dissipation performance of the L-shaped specimens, the seismic behavior of the joints is studied, and it is concluded that the L-shaped joints are relatively difficult to destroy under this load. Has a certain safety. The nonlinear finite element analysis of a new type of composite concrete-gypsum board wall panel L shape specimen is carried out by using the large and universal finite element analysis software ABAQUS, and the results are compared with the low cycle repeated test results, and the results are in good agreement with each other. It provides a reference for computer simulation of other specifications of new composite concrete-gypsum wall panel low-cycle repeated tests.
