Paper Title:
A Setting Pre-Angle Method in Multi-Steps Construction of Long-Span Steel Structures
  Abstract

Many long-span structures have to be divided into several substructures to manufacture simultaneously and ensemble by multi-steps. Based on the engineering practice that pre-angles can be set at joint nodes between pre-erected and after-erected substructures by inter-node design, this paper proposes that the pre-erected substructures can be analyzed independently with finite element method(FEM) to ensue safety of the semi-complete structure system, and the displacement of joint nodes can server as boundary constraint of after-erected substructures after the rotational components are relaxed, the theoretical basis and solution algorithm is described also. The analysis of a typical case proves that this method make the after-erected substructures facilitated more easily.
