Wind Resistance Research and Wind Tunnel Test of Large-Span Roof Based on Yancheng Financial Center

A large number of buildings with large-span or complex-shape have come to the fore in recent years. To these structures, wind load tends to be control load in the structural design. Shape coefficient of wind load which Chinese load code for the design of building structures can provide is extremely limited due to complex-shape of long-span space structures, therefore carrying our related study is of great practical significance. Yancheng Financial Center model is established in this paper based on ETABS software. The acquired date in the use of wind tunnel test is to simulate wind load which is on the structure and to analysis stress distribution of critical element in order to ensure safety and applicability of structures. This paper mainly covers wind tunnel test, equivalent static wind load, and wind-induced response, etc.
