In the steel reinforced concrete members, since the main reinforcement in beams may pass through the steel web and flange of the steel reinforced concrete columns, perforation in the section steel can't be avoided. When the perforation ratio of the hole is large, it is necessary to strengthen the section steel. The regular practice is to welding the reinforcement plates to the main steel column with...
The fine blanking process with stepped-edge punch was analyzed by finite element method for different curvature parts. Distributions of hydrostatic stress on deformation zone were obtained for different curvature parts. An experiment device has been designed and made for one automobile part by fine blank process with stepped-edge punch. The reasonable forming parameters were adjusted according to...
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...
The electrostatic precipitator used in the power plant is the important environmental protection facility to eliminate the flue gas. The casing is the most important technical component. The load bearing mechanism of casing is very complex. The overall load bearing performance of the casing structure is conducted by finite element method. The results of eigenvalue buckling analysis indicate that the...
The simulation model of hot rolling coupling was established using finite element method base on studying and analyzing of universal rolling method for H-beam. The distribution of temperature field and stress field in contact area as the main research subjects during hot rolling under the given rolling regulations of H-beam, the whole process of hot rolling was completely simulated. The results show...
