| 摘 要： | 以居住建筑保温工程中一个典型开间的外墙为研究对象,采用有限元数值模拟方法,分析了EPS板薄抹灰外墙外保温复合墙体在夏季极端高温、骤降暴雨环境下的热结构耦合反应,结果表明:外界不利环境是引起裂缝或脱落的主要因素之一;聚苯板具有良好的隔热效果;窗洞四角变形较大,是容易出现问题的地方,应当引起重视;由于砂浆与EPS板的交界处变形不协调,裂缝会首先出现在砂浆层或者与EPS板的交界处.

| Abstract: | This paper simulates thermal-structural response of the outer wall of a typical residential building in the summer high-temperature and rain environments using finite element analysis methods.The results show that external bad environment is one of the main factors;that polystyrene board has a good thermal insulation effect;that the displacement of the four corners of the windows is larger which must pay attention;that the deformation between mortar and EPS board isnot coordinated,so the cracks is appeared ... |
