Scientometric Analysis for Mechanical Performance of Broken-Line Long-Span Steel Structure in Construction Considering Geometric Nonlinearity

A structure does not reach a stable state during the construction process, and hence its structural reliability is low. In order to ensure safety of process final quality, it necessary analyze mechanical properties large-span space steel structures process. Based on engineering background polyline symmetrical this research established finite element model an ANSYS platform. The correctness was verified by comparing measured frequency with calculated in model. life-death method, internal force deformation response characteristics were analyzed, different effects on-time completion step-by-step performance broken-line compared analyzed. study found that long-span truss more sensitive forming greatly affected sequence different, size distribution stress are also different. analysis result closer actual project. Therefore, appropriate paths should be used reduce impact path performance. It recommended pay attention displacement when encounters similar in-place construction.
