A fire in a storehouse was simulated numerically. Air temperature elevation caused by the fire was determined for different locations in the storehouse using FDS software. By comparing with the empirical formula of temperature elevation in large space fire, it was shown that when the fire location is close to the wall, the spread of the smoke will be blocked, resulting higher air temperature beside the wall. The behaviour of the roof structure of the storehouse, a cylindrical lattice shell, under the fire was analyzed by using finite element method. The local damage of the lattice shell predicted by the numerical study agreed very well with the field investigation, which verified the accuracy of the numerical simulation of the fire scene and the finite element analysis. Suggestion was provided for the repair of the lattice shell, based on the damage estimation of the lattice shell after fire. Source

The Xidi project of Tianjin has an underground parking garage, and its foundation pit is about 9 m in depth with a span of over 120 m. It is difficult to use project with internal support. So the self-sustaining double-row piles are used, and they are convenient for excavation and construction. Some problems about the design and construction are introduced, and the observed results of the excavation are analyzed and summarized. Source
