External components loss injuries caused by various defects of steel material performance, design, production and construction, and adverse factors such as overloading, repeated load, high-temperature, corrosive media or mismanagement, direct impact on security of steel structure in the course of subsequent use. Based on the investigation of single layer steel structure industry workshop, from two aspects of nature and quantify, the effect of initial geometry defect on bear of axle pressure component and crane runway partiality on bear of crane beam system is analyzed, which is the basis of regularity uses、consolidating and monitors of the building. The result shows that through the computation of axle pressure component with initial geometry defect or crane runway partiality, the component's bearing capacity reduces many and the effect of security is big, and when the initial geometry defect or crane runway partiality surpasses the standard stipulation the certain proportion, bearing capacity will continue to reduce, the structure will be more unsafe. The effect of crane runway partiality on the crane beam web plate upper extreme edge's intensity and web plate horizontal stiffening rib's intensity is little.
