Generally laminated wood frame beam-column uses the additional steel bolts to connect, its performance is a semi-rigid characteristics under the loads. In the small deflection assumption conditions, this paper is based on the theory of semi-rigid connection, derived the semi-rigid rod end stiffness matrix and moment calculation formula of laminated wood structural frame beam-column element under the arbitrary loads. By SAP2000 the type of flexible coefficient is adopted to establish finite element numerical analysis based on 1# wood frame structure-building of science and technology R&D center in Hebei province. The result shows that each component is basically the same with the original design internal forces while the flexible coefficient is range of 0.41 to 0.82, the framework of semi-rigid connections in the actual calculation should be considered. The internal force calculation method is proposed, which provide a basis for wood design calculation that takes into account the semi-rigid connections.

In frame structure, the Supports of secondary beam are frame beams or main beams, Support Beam rotation of the secondary beam to form certain constraints. General calculation method, for edge Supports, sometimes as fixed or hinged, the so-called “method of taking no account of torsion rigid”. In such cases, intermediate supports are usually as hinged, obviously not reasonable. We consider the torsional characteristics of all supports, according to torsional stiffness of the beam support. Therefore, we can become the continuous beam mode into the frame mode, so as to simplify the calculation, analyzed the influence of the torque, and should pay attention to the problem.

Steel Frame Structure

Most steel beam-column connections actually show semi-rigid deformation behavior that can contribute substantially to overall displacements of the structure and to the distribution of member forces. Steel frame structure with semi-rigid connections are becoming more and more popular due to their many advantages such as the better satisfaction with the flexible architectural design, low inclusive cost and environmental protect as well. So it is very necessary that studying the behavior of those steel frame under cyclic reversal loading. On the basics of connections experiments the experiment research on the lateral resistance system of steel frame structure has been completed. Two one-second scale, one-bay, two-story steel frames with semi-rigid connections under cyclic reversal loading. The seismic behavior of the steel frames with semi-rigid connections, including the failure pattern, occurrence order of plastic hinge, hysteretic property and energy dissipation, etc, was investigated in this paper. Some conclusions were obtained that by employing top-mounted and two web angles connections, the higher distortion occurred in the frames, and the internal force distributing of beams and columns was changed, and the ductility and the absorbs seismic energy capability of steel frames can be improved effectively.

Taking a 5-story reinforced concrete frame structure on the transformed 3-layer steel frames for an example, use finite element software ANSYS to reformation as a whole building model under static wind load changes for comparative analysis of internal force and displacement of the corresponding node. Analysis results show that in the transformation of steel on reinforced concrete frame structure, should fully take into account the structural stiffness change on construction of the overall effect of wind resistance, so that the transformation of the steel concrete frame structure more reasonable.

Reinforced Concrete Frame Structure

Basing on the finite element analysis software, the emergence of crack under the effect of gradual changed temperature load and the change of stress which are in the condition of super reinforced concrete frame structure are analyzed from the linear and nonlinear numeral simulation. The simulation shows that the structure component under the normal condition is cracked and turn into the nonlinear condition and the steel bars still works under the elastic stage. Meanwhile the actual stage which is reflected by the elastic-plastic analysis of the internal force and deformation is compared by the results which are obtained by the actual project observed results and the calculation of the simplified model. So the distribution of the stress which is caused by the structure temperature reduction is greatly evaluated by the usage of the cracking model which is nonlinear finite element and also plays an important role in the engineering project and practice.

In this paper, the influence of foundation stiffness on the seismic behavior of shear wall-frame systems was investigated. First, a basic differential equation was established to account for the interaction between the foundation and superstructure. By solving the equation, the influence of foundation stiffness on the lateral stiffness, inter-story drift, and internal force distribution of the superstructure at the elastic stage was elucidated. Subsequently, the concept and method for determining the range of foundation stiffness suitable for shear wall-frame systems were proposed. By taking a 12-story shear wall-frame structure built on a shallow foundation as an example, a parametric study was performed for various frame-to-wall relative stiffness ratios and foundation stiffnesses. The effect of shallow foundation stiffness on the base shear distribution and energy dissipation of the superstructure was clarified, with results compared with those of the fixed-base model. The analysis results indicated that the degeneration of foundation stiffness due to earthquake damages will result in significant redistribution of internal forces, namely, the internal forces of the walls decrease, while those of the frames increase. In particular, the shear-force and bending moment of the bottom frame columns rise drastically, which may greatly reduce the safety margin and should be considered in practical design.
