There is not a complete set of computational and analytical method on steel fiber concrete simply supported Wall-beam, the steel fiber concrete simply supported Wall-beam performance and working conditions is only a small number of test results through the analysis obtained. As the test equipment, the test methods and other factors directly affect the reliability of test results, therefore, there...
The static and dynamic load tests are carried out on the bridge. The calibration is obtained when the deflection with static load and structure frequency with dynamic load are analyzed and are compared with finite element analysis results. Both strain calibration and deflection calibration meet the requirements of the relevant standards of the bridge engineer manual. The maximum deflection meets requirements...
According to the theory of the thin plate and beam bending of elastics mechanics and taking the hypothesis of G.kirchhoff into account, a finite element model of the platform is built. Based on the theory of deformable body mechanics and kinetics, the formulary for the mass-center elastics displacement of the platform caused by deforming was deduced. Depending on the theory of the spacecraft attitude...
According to the fact that the ballastless track system study results often deviate from the actual value greatly using the method of simplified box girder in the high-speed railway at present. The new overall 3D models with simple box girder and ballastless track slab are built by using ANSYS software, and dynamic response results of ballastless track slab in the overall structure are analyzed at...
The crane performance depends largely on its box girder structure. The problem of structure topology optimization for a box girder is investigated in this study. Firstly, a comprehensive analysis to box girder is given and a topology optimization model for the bridge crane girder structure is established. Secondly, based on the optimization model, the box girder is optimized with finite element software...
A precast, prestressed concrete girder with circular web openings allows building service systems (mechanical, electrical, communications, and plumbing) to cross the girder line within the memberpsilas depth, reducing a buildingpsilas floor-to-floor height and the overall height of the structure. These height reductions have the potential to improve the competitiveness of total precast concrete structures...
