Numerical Study on Mechanical Properties of Novel Umbrella Structure
摘要
Novel umbrella structures (NUSs), developed from the traditional umbrella structures, were designed and used in the Jixiang service area of expressway, Heyuan Ctiy. To verify the mechanical properties of NUSs, this paper used numerical software called ABAQUS to calculate the mechanical properties of NUSs under design load. The calculated results indicated that the concrete did no cracked under design load, and the steel and rebars of NUSs also did no reached the yield stress of those. The NUNs were safe under design load.
