Abstract


With China's rapid economic development and the increase of urban population, high-rise and high-rise building occupies an extremely important role in the construction of the modern city, its beautiful gesture to attract people's attention. Mixed structural system is a new type of structural system in the country in recent years and has developed rapidly, mainly for high-rise and high-rise buildings. Compared to the concrete structure, mixed structure has light weight, small section size, structure force performance improvement and construction speed advantage; compared to pure steel hybrid structure has a good fire performance, with low total steel low cost, wind loads and good comfort. Tall hybrid structure gradually become a hot high-rise buildings in the modern city, but due to the high concentration of personnel in high-rise buildings and wealth, once an earthquake, its disasters are devastating, in the high-level structure, the seismic design of the structure is essential . In this paper, the framework of a 48-story high-rise steel reinforced concrete - concrete core wall hybrid structure analysis of the seismic performance of high-rise buildings mixed. The ETABS large finite element software, according to the actual size of the structure and the stress state a senior steel reinforced concrete frame - concrete core tube mixed three-dimensional finite element model of the structure; dynamic characteristics given order modes Figure to show the structure of natural vibration characteristics; explore the relationship between the modal participation structure reaction; take the combination of the first 20 modes to analyze the dynamic response of the structure; discussed the impact of the higher modes of structural response magnitude and regularity. Structure unidirectional, bidirectional earthquake vibration response spectrum analysis and one-way, two-way seismic waves elastic time history analysis; study the structure of the internal forces in the role of multi-earthquake, deformation and torsion properties; and compared the results of analysis of the response spectrum analysis with flexible schedule; discussed the structure in a multi earthquake under small earthquakes are not bad, \MIDAS / GEN finite element software structure the Pushover analysis; take modal loaded with acceleration constant load two lateral loading, internal forces and deformation of the structure in a multi earthquake rare earthquake the development and distribution of plastic hinge law;, and single-mode calculation results with the multi-modal pushover analysis method results were compared; find out the distribution of plastic hinge structure under rare earthquake area, the structure of the weak layer analysis of the failure mechanism of the structure.
