【摘要】 引起钢筋砼梁裂缝的原因很多 ,如设计失误、施工不当、材料不符要求、使用功能改变等均可导致梁出现裂缝。但部分设计失误往往比较隐蔽 ,一般人事先难以发现 ,或发现较晚 ,故带有更大的危害性。本文作者就多层民用建筑中部分因设计失误导致计算简图与实际受力不符的梁裂缝问题进行重点分析。更多还原

【Abstract】 There are many reasons causing reinforced concrete beam crack,for example,design mistakes,construction wrong,materials out of needs,changing using function,etc.all the factors may cause beam crack.But partial design mistakes are often hidden,found hardly early,or found late,therefore,they are more dangerous.Partial design mistakes may cause computation model disagreeing with practical force.In this paper,beam crack problem because of partial design mistakes will be comprehensively analyzed.更多还原
