Analysis of Wind Loads Acting on Large Span Double-Arched Roof Structure with Opening Ends

Due to the complexity of large span double-arched roof structure, Chinese load codes are not enough for the design. Other method should be used to ascertain the wind load on the roof structure. Computational fluid dynamic (CFD) is a newly developed research method for wind loads. The distribution of wind pressure and wind environment on the roofs of large span double-arched structure were computed based on ANSYS-CFX12 software platform with Reynolds stress model(RSM). By the simulation, the unfavorable wind shape coefficient is obtained which help the designer to enhance the key component for the safety of the serviceability performance.

Analysis of a New Wedge-Shape Rectangular Tube Column and Girder Connection Joint

Aiming at the existing problems of column-beam joint put forward the new wedge-box joint. The new joint shape is simple, avoid the inconvenience that add diaphragm in the square tube, as well as to the late process of building interior decoration, the way of joints force transmission is clear, mechanical and seismic performance is good, from the external shape is better than the traditional internal partition and outreach plate joints, and compare to the both, inner bearing capacity is not weak, it can satisfy the need of industrialization of steel structure well, and used in actual engineering design.
