Abstract


Steel structure with a high degree of industrialization , construction speed , modern industrial plant construction , a large number of steel structure plant. The ordinary steel roof truss structure plant its rigidity , integrity , good features, widely used in the structure of the steel mills and room . Ordinary steel roof truss structure of the roof of the plant can be divided into no purlin roof purlin roof roofing materials and roof layout . Home and abroad for the single-layer steel plant roof system has been very mature , but for most of the heavy steel room , roofing systems or traditional precast concrete roof , heavy steel housing with lightweight roofing less . Light steel structure technology development , makes light of a steel structure of the main direction of development . STEEL ROOFING lateral stiffness and performance , guarantee , lightweight roofing system meets the steel structure the mainstream of development . The finite element model purlin roof , and no purlin roof steel structure plant , static and dynamic analysis . Static analysis to create a three-dimensional model , the use of finite element analysis program for static analysis of four different levels of stiffness roof monolayer plant structure . In the same member section , static characteristics of plant length and span different analytical structure , and the results of comparative analysis . Dynamic analysis using modal response spectrum analysis of four different levels of stiffness roof the monolayer plant structure . Changing the length and width of the plant to discuss the dynamic characteristics of various length and span of four stiffness roof plant structure and dynamic response . In the feasibility purlin roof purlin roof and no purlin roof plant structure analysis and comparison on the basis of the evaluation the longitudinal horizontal support strengthen purlin roof instead .
