Grading Executive Stress Analysis Of Frame-supported Frame Structure

At present, to satisfy increasing requirement of high-rise, transfer layer is widely used. Herein girder-style transfer layer is the most popular structure. Because of vertical force transfer existing in transfer structure, the force of structure is more complex, especially during the construction stage. Construction stage is never considered or considered simply in many calculations, which causes design can not reflect practical state.Pushover module of Sap2000 is used to analyze girder-style transfer layer in this thesis. Model defined in construction stage is identical to construction stage as far as possible to obtain force performance of girder style transfer layer during different stages in practical construction.Meanwhile theoretical research of girder style transfer layer is also introduced in this thesis , which mainly includes: static elastic plastic analysis Pushover theory, plastic hinge, P-Δeffect and analysis theory in construction stage. Development trend of girder style transfer layer in the future is forecast. Business of transfer layer should be noticed during construction stage is introduced. By taking practical project as example, force performance of transfer layer of concrete is analyzed, and integrated performance of overall project structure is calculated, analyzed and simulated. For girder style transfer layer, calculation result obtained by considering construction stage and result obtained by typical integrated analysis is compared. All kinds of factors (such as concrete intensity and difference of construction period etc.) are considered too. Therefore effect of simulating and analyzing considering construction stage on girder style transfer layer is obtained.Conclusion is drawn by comparing analysis result with considering construction stage and without construction stage. Suggestion is proposed for design and construction.
