This article used ABAQUS finite element analysis software to established the high-formwork, analyzed effect on stability of the different height formwork by contrasting lateral displacement of various heights, discussed influence of concrete pouring sequence on stability of different height high-formwork support system in the construction process. From the simulated result, it can be seen that with the increase of height, the lateral displacement increased gradually when poured in dissymmetrical way, but the stability of high-formwork decreased, the result also provides evidence for code revision.

Maximum Lateral Displacement

ANSYS finite element analysis software is used to simulate the changes of maximum lateral displacement of the high-formwork support system in different sequences of pouring concrete. In the condition of loading which was applied from one side to the other side, the maximum lateral displacement of the frame had a sudden increase in each loading process. In the condition of loading which was applied symmetrically, the maximum lateral displacement of the high-formwork steadily rising nearly straight with the load applied. So the symmetrical pouring concrete ways is better for the whole stability of the high-formwork.

The Stability

The optimum shape of the tunnel is usually decided by many factors. Not only should it ensure the stability of surrounding rock and the advantageous of masonry's stress, but also it need to meet the using requirements of the cavern, the convenience of the construction, the least excavated volume and the best economic results. Seeking the optimal shapes of the carven which is under the specific condition has always been paid great attention by engineers. With the help of ADINA finite element analysis software, this paper imitates related data in elastic theory about the excavation of tunnels with the typical planes of fracture which are under the same geology condition. After that, it contrasts the actual computing results with the theoretical analysis, and then studies planes of fracture's optimal excavated shapes of the tunnels.

The Stability

Bridging play a important role in guarantee the stability of the high-formwork support system as a whole, its arrangement location will affect the force of the frame body. This paper used the finite element analysis method to compare the bridging arrangement location under the beam with the bridging under the board which was arranged according to certain modules. the results show, the arrangement spacing of the bridging under the beam is greater than the bridging under the board, but its frame body lateral migration is smaller, sharing part of the axial force of beam bottom rod at the same time, that means the bridging under the beam is more beneficial for the stability of high-formwork support system.

Specification Requirement

This study is pointed to a computer table with five degree of freedom. The table position could be adjusted freely. The height of the tabletop also could be moved freely. The finite element analysis software ANSYS was used to analysis the strength and rigidity of the computer table. From the analysis results, it can be found that the strength and rigidity were fit in with the specification requirement with a safety factor of 1.20. From the modal analysis results, it also found that the stability of the computer was confirmed to the users.
