The following paper analyzes the causes of cracks in concrete masonry infill wall with frame-structure from temperature fluctuation,the change of water content,construction quality,and the quality of construction material,and proposes related preventive measures,in order to improve crack-resistant ability of infill wall and guarantee structural integrity.

Fromtemperature,shrinkage,the corrosion of reinforcingsteel,construction materials and other aspects the reasons causedthe con-crete cracks producedin construction process are analyzed;at the same ti me corresponding prevention and treatment measures are introducedfromraw material control and construction technologyin order toi mprove engineering quality and reduce loss.
