Comparison And Analysis Of Structural Schemes Of One Out Of Super-high-rise Buildings

Frame-core tube building structure system often use the building equipment layer,the refuge layer and other structures with greater rigidity of the structural strengthening layer,that is,in the floor core and the external frame structure between the column out of the horizontal extension of the arm or along the periphery of the surrounding ring Reinforcement layer.The reinforcement layer can be strengthened to strengthen the connection between the core tube and the surrounding thin column frame,so as to improve the lateral stiffness of the whole structure,But in the earthquake,the strengthening layer settings can cause structural rigidity and internal forces of mutation,easy to form a weak layer structure,Therefore,in the barrel earthquake zone-Frame Structure Design dilute column,whether to adopt a reinforcing layer,how reinforcing layer,reinforcing layer seismic performance of how to ensure the position,must be dedicated to computational analysis.Anhui Bengbu S6 plots of commercial and residential buildings,above the ground level of the total number of 54 layers,the use of steel reinforced concrete frame-reinforced concrete core tube structure system,the main roof height of 180m,more than 7 degrees frame tube structure area 130 meters height limit class A,And has to reverse the irregular,local wear column and so on.This article works for this study,the following research work:Chapter 1:Describe the current theoretical system of seismic design,and refer to the relevant theoretical literature,a brief summary of the mechanism and advantages and disadvantages of the structural strengthening layer.Chapter 2:Building and structural design scoping study engineering,structural overrun discrimination based on relevant norms.Chapter 3:According to the construction conditions to complete the structural system layout,the establishment of research project overall elasticity calculation model.Chapter 4:At the beginning of the structure calculation model based on the structure in order to control the displacement angle control index,comparing different location,number,type of horizontal layers just to strengthen the role of the layer structure,come to the preliminary plan designed to strengthen the layer.Chapter 5:Using the performance-based seismic design method,comparing and setting up two different design schemes without structural reinforcement layer,the seismic performance target is determined,and the elastic time history analysis and dynamic elasto-plastic time history analysis and comparison whether it satisfies a predetermined seismic performance objectives and requirements.Chapter 6:Based on the conclusion,it is concluded that "the reinforcement layer should only be used to make up the rigidity of the original structure,and the rigidity of the original structure should be adjusted as far as possible".The seismic design of the similar structure can provide some reference.
