混凝土小型空心砌块建筑温度效应分析和研究

FINITE ELEMENT ANALYSIS OF TEMPERATURE EFFECT OF BUILDING OF SMALL CONCRETE HOLLOW BLOCK

结合杭州混凝土小型空心砌块多层住宅试点工程的设计 ,针对设计方案中所采用不同的构造措施 ,建立相应的有限元模型。考虑南方地区的气象和气候条件 ,参考已有的试点建筑温度场分布 ,进行温度效应的有限元分析。从而得到试点建筑中温度应力的分布 ,为南方混凝土小型空心砌块建筑温度裂缝控制提供设计依据。

In this paper, the corresponding finite element models can be set up according to the test project of multi\|story housing building of small concrete hollow blocks. Under the climate of the south, finte element analysis of temperature effect of concrete hollow block system can be done. We can get the law of temperature stress distribution in the wall according to the corresponding models to different control methods, which will provide a theoretic basis for the temperature crack control of this sort of building.
