Reliability Analysis of High Rise Building Considering Wind Load Uncertainty

In engineering structures, the safety problems are always depending on the respond of structures to different types of load.The safety assessment of a high rise building is highly depending on the analysis of environmental load. Many codes andpractices have proposed many requirements for engineers in the design works. These include safety factors, limitations ondamage, maximum deflections and so on. When violations in these requirements occur, the structure is believed to bedangerous. But once the problem becomes complicated such as multiple unknown loads in one building, it requiresreliability analysis in the design. It must take care of all the assumptions and uncertainties in the structural design. Inprobabilistic assessment, any input variable is considered as an uncertainty. However, the traditional way to deal with theseproblems may have problems when uncertainties are large. Many probabilistic safety measures need to be reconsidered inengineering work. This paper, we will provide reliability analysis on a high rise building with consideration of wind load.All the most commonly applied reliability methods are been utilized in this analysis and compared base on the performance.The statistical influences including correlation and distribution type are also discussed in the same reliability problem.
