[關(guān)鍵詞] 混凝土空心小砌塊溫度裂縫 有限元 構(gòu)造措施In order to resolve the cracking of concrete hollow pint-sized brick building, this paper adopts FEA to analyze diverse constructional details in concrete hollow pint-sized brick wall, from which we can find out the distributions of displacement and stress and the functions of these constructional details to find the best project restricting the wall's displacements and preventing cracking of the walls. Calculated results will be compared with experimentation to find out the best crack-controllig methods, which will provide a lot of reference data for design and construction.
Keywords: concrete hollow pint-sized brick; temperature crack; finite element analysis; diverse constructional details
