Steel is also a time of damage, we have to immediately find the immediate solution to the problem, and the steel structure of the main factors of Steel Space Frame For Gymnasium damage are:
1) The bearing capacity is not enough due to the change of load, overtime service, specification and procedure change;
2) Components due to a variety of unexpected deformation, distortion, disability, depression, resulting in weakened cross-section components, rod warpage, connection cracking;
3) The temperature difference caused by component or connection deformation, cracking and warping;
4) Corrosion due to corrosion of chemical substances and electrochemical corrosion caused by weakening the cross-section of steel structure;
5) Other including design, production, construction errors and service during the illegal use and operation.
Reinforcement of Steel Space Frame For Gymnasium measures are mainly three kinds:
1) Cross-section reinforcement method: in the local or along the full length of the steel reinforcement, even as a whole so that the common force;
2) Change the calculation diagram: add additional support, adjust the load distribution, reduce the internal force level, the statically indeterminate structure bearing displacement, reduce stress peak;
3) Prestressed cable method: Steel Space Frame For Gymnasium the use of high-strength cable reinforcement structural weak links or to improve the overall bearing capacity, stiffness and stability.
