【摘要】 建筑节能是建设领域贯彻科学发展观，建设资源节约型、环境友好型社会的重大举措，是实现社会经济可持续发展的重要组成部分。提高建筑维护结构的保温性能是推广建筑节能的重要体现。近几年来，新型墙体材料和节能住宅建筑体系如雨后春笋般发展起来，但截止目前在全国新型墙体材料和节能住宅建筑体系使用的比率还不高,目前已有的新型墙体材料和节能住宅建筑体系都还存在诸如保温层开裂、渗漏、腐蚀、老化、寿命低于建筑物寿命等耐久性问题和未能很好解决冷桥等问题而在推广方面受到制约。因此,研究和开发新型节能住宅体系是十分必要和有意义的。本文研究一种集保温、承重功能于一体的构建建筑结构性能优良的夹芯板——钢筋网架—混凝土组合夹芯墙板的主要性能。首先，本文进行2个受弯试件的单调静载试验，得到楼面板和屋面板的挠度曲线、极限承载力等性能；然后采用有限元分析软件ANSYS对等尺寸的受弯楼板试件进行非线性有限元建模分析，将各试件的试验结果与有限元分析结果作对比分析，结果表明WZ组合墙板具有良好的抗弯承载能力，可以满足作为屋面板、楼面板的使用功能。其次，进行2个轴心受压试件和1个偏心受压试件的单调加载试验，分别研究组合板的轴心受压和偏心受压等力学性能；并基于有限元分析软件ANSYS对等尺寸的受压墙板进行非线性有限元建模分析，对各试件的试验结果与有限元分析结果作对比分析，分析表明该组合墙板受压性能良好，具有很好的协同工作能力。最后，进行2个热工性能试验研究组合墙板的保温性能，并与有限元分析结果作对比分析，分析表明该组合板保温性能良好，满足国家规定的建筑节能保温的要求。更多还原

【Abstract】 In the construction field, energy efficiency is an important measure ofimplementing the scientific outlook on development and building resource-savingand environment-friendly society, as well as an important part to achievesustainable socio-economic development. Furthermore, improving the insulatingperformance of building maintenance is an important manifestation of promotingbuilding energy efficiency. In recent years, new wall materials and energy-savingsystem for residential buildings are springing up development, but up to now theirresidential use rate has not been high in our country; one of the reasons is that theystill have many problems such as insulation, leaks, corrosion, aging, life expectancylower than the durability of buildings and so on, which results in the limitation intheir promotion. Therefore, research and development of new energy-savinghousing system is very necessary and meaningful.This paper studies the main performance of Bar-Reinforcing-Net sandwichconcrete panels, which is a kind of sandwich wall with excellent performance ofthermal insulation and load-bearing functions.First, this thesis obtained the deflection curve, ultimate strength and otherproperties of floor and roof panels through two monotonic static tests for bendingspecimens. Two non-linear finite element models of bending specimens were builtand the corresponding numerical analysis used the ANSYS software. Thecomparison between the numerical and testing results for each of the specimenshows that the composite wall panels have good bending ability suitable for use asroof and floor panel.Second, the performance of the composite panels subjected to axial andeccentric compression was studied through the corresponding monotonic loadingtests of the panels. Similarly, this thesis built the non-linear finite element models ofthe specimens, and the corresponding FEA results ware compared with the testingresult was done. Also it shows good compressive performance and interoperabilityof the sandwich wall panels.Finally, thermal insulating performance of the panels was studied through twodesigned tests, which is compared with the corresponding finite element analysis results.The comparison indicates that the sandwich wall panels have good thermalinsulation performance and energy efficiency and meet the national requirements ofinsulation requirements.更多还原
