When lightning strikes the building the lightning electromagnetic pulse (LEMP) will generate in its internal three-dimensional space, and it will cause different intensity transient over-voltage and over-current in various electrical and electronic device through conduction, induction and coupling, thus affecting the safe and reliable operation of the equipment. In order to study the indoor three-dimensional...
In this paper, McCaffrey plume model is introduced to calculate convection heat flux to large span steel structure during fire, and a critical temperature is defined, below which the stress calculation could be omitted. It's also suggested that the impact of the failure of a certain section on the whole structure should be considered. Such method is applied to the fire safety analysis of the large...
To improve the seismic design of steel frame structures, the empirical formula for evaluation of fundamental periods of steel frame structures was investigated and a new formula was presented in the paper. A total number of 36 moment resisting steel frame structures were selected for the statistical analysis, and all the structures obtained seismic response records during past earthquakes. The fundamental...
Using material with unique ways may tremendously improve the behaviors of a building. Aiming at the weakness of the existent residential building systems with steel structure, such as weaker structural stiffness, obstructing the indoor space being used, affecting the appearance of interior facade, a new conception of a congregated residential building system with special-shape section steel structural...
Stability bearing capacity analyses of cold-formed purlins with conventional specification and span are performed under wind uplift load. The analyses are performed on the stability bearing capacity of C- and Z-shaped simply supported purlins. The comparison indicate that the formulas of specification are considered to be conservative between results of finite element method and that of design formulas...
