To study the influence of flame radiation on temperature rising of steel members in large space building fire and to find the simplified estimation,this paper calculates over 6000 sets of parameters using the heat equilibrium equation.

Full-scale burning tests and numerical simulations were carried out to study the movement of smoke under a hot air layer in large space fires in summer.

Full-scale burning test and numerical simulation were carried out to investigate the mechanical exhaust in large space fire with one-side unsymmetrical air supply.

To study smoke control, the large space fire experiment hall of university of science and technology of China was equipped with three fixed speed fans and an alterable speed fan.

Design of performance-based smoke management of large-space building;

The heating systems that are applicable in large-space buildings are introduced, and the characteristics of floor radiant heating system and gas-fired infrared radiant heating system that are applicable in large-space buildings are analyzed.

Zero equation model is applied in thermal environment simulation of large-space buildings.

Comparison of calculation models for smoke temperature in fire of large space building;

Numerical simulation and thermal comfort analysis of indoor air distribution in large space buildings;

Discussion on the construction of double spiral duct in large space buildings;

Analyses the parameters of fire temperature elevation at the top of large space buildings;

Water sprinkler effects on smoke layer in large space fire;

Measurements of indoor thermal environment and energy analyses of a large space in winter conditions;

Experimental study on efficiency of smoke exhaust in large space buildings;

Biochemical terror patterns in public large space buildings include firing to produce poisonous gas,exploding gas bomb to spread poisonous materials and artificial distributing poisonous materials directly.

With the increase of large space buildings,more and more energies are consumed.
