STUDY ON CONSTRUCTION SAFETY AND SIMULATION OF LARGE-SCALE STRUCTURES

In construction process of large-scale structure, the constraints, loading and mechanical behavior of the uncompleted structure is quite different from that in normal service condition. It may be not safe to evaluate the partially erected structure and its components by using the completely erected condition. In addition, since structure deformation is cumulated in every step, the ultimate shape of the structure may not meet the design request. Thus, analysis methods that can exactly simulate the true construction process step by step should be adopted. Only by using the proper simulating methods, the safety of partially erected structure and the ultimate shape of design request can be certified. In this paper, practical researches of construction simulation methods are carried out based on real projects. Finite element analysis software ANSYS is adopted to actualize the simulation methods in construction analysis by using the technique of birth and death of elements.
