- Abstract:
- This paper focused on the early construction risk warning issue in the construction of super high-rise building,the potential failure of the system was studied according to the general state and radical state.Taking the load-bearing components of integral steel platform equipment as the key risk link,a construction risk early warning index system and method for super high-rise building were proposed.Firstly,based on the analysis of accident evolution path and failure mode considering the coupling effect of risk factors,the core indexes were proposed,combined with the monitoring conditions.Then,the early-warning index system including human,environment,equipment and fuse indexes,as well as the classification and determination criteria,are proposed.The way of reducing index was adopt to reflect the impact of multi-factor coupling effects,and applicable early-warning method was established.Finally,a project was chosen to carry out case analysis.The results showed that the method of considering the coupling effects of human and environment risk factors as a reduction of the equipment indexes could be used as effective basis for judging the risk status of the project,to establish a risk early-warning method suitable for the construction of super high-rise buildings.This method fully considered the coupling effects of risk factors,and obtained values of early-warning indexes and reduction coefficient table through finite element model calculations.It was feasible.
