钢筋混凝土构件的安全定性分析初探

The Qualitative Analysis of the Security of Reinforced Concrete Structures Preliminary

房屋安全鉴定是一项技术与政策相结合、局部和整体相结合、必须考虑诸多因素的技术工作,对房屋钢筋混凝土构件进行鉴定,自然离不开对其强度、刚度、抗裂性等进行定量测算,必要时还应通过荷载试验,但在实际工作中,往往是首先通过现场踏勘进行外观检查,这不仅可以在房屋安全鉴定中起到事半功倍的作用,提高办事效率,而且对如何鉴定裂缝、分析裂缝、控制裂缝也有一定的指导作用。

Housing safety appraisal is a technical work combining with technology and policy, local and overall ,and should be considered many factors. On the evaluation of reinforced concrete structures its natural strength, stiffness, cracking, etc. should be quantitative estimated, if necessary, load test should also be performed.But in practice, we often have the visual inspection through the site reconnaissance at first, which not only play a multiplier role in the identification of housing safety, improve efficiency, but also has a guiding role in how to identify crack, crack analysis, crack control also.
