The paper presents the process of the load-bearing experiment on a large-scale space truss in-site, which is for ensuring the structure to meet load-bearing capacity requirement specified in relevant code and conduct the safety appraisal.

With the development of the economy and constant progress of science and technology,application of large-scale space truss structures in buildings is more and more extensive.

Roof isolation is put forward in this paper based on the characteristic of the long span space truss structure.

Temperature stress of spatial grid and design of supporting block;

In view of priority and characteristics of spatial grid roof structure,applying grid structure and light roof to roof between turbines in main building of power plant and substation control building is becoming popular.

The research on calculating accurately space truss considering partial tensile compression rigidity;

Damage identification of space truss with incomplete measured data

However, the present designers in space truss often estimate the temperature force, but fail to carry out accurate design for it.

In order to improve the horizontal seismic performance of long-span space truss structures,the horizontal seismic isolation method is put forward with regard to the good mechanical properties of the lead laminated rubber bearing,which incorporates the bearing into the structure between the upper space truss structure and the lower supporting structure.

This paper provides a new way of hoisting - hoisting by handle pulley and analyzes experience that is worth spreading and problems paid attention to in hoisting on large net frame by introducing hoisting plan of refined coal shed in a coking factory in Jilin province.
