Application of reinforced concrete structure in high-rise building structure

Reinforced concrete structures and steel structures are mainly used in high-rise buildings in China. However, the traditional reinforced concrete structure has some disadvantages that can't be ignored: the consumption of building resources and energy is large, and the environmental pollution is serious during construction; Large labor input and low construction efficiency; Insufficient earthquake safety; The construction cost is high and the economy is difficult to guarantee.

In order to solve these problems, the project team composed of Chongqing University, CCDI and other units lasted for nearly 20 years, and achieved a series of innovative results through a large number of model tests, theoretical research, numerical simulation, design theory and method research, software development and engineering practice.

A new braced mega-frame-core-tube structure system suitable for super-high-rise buildings and its design calculation method are proposed, which solves a series of design technical problems such as the calculation and analysis of cross-grid-core-tube hybrid structure system, the influence of deformation difference of vertical members and concrete creep on high-rise and super-high-rise hybrid structures, the stiffening method of thin-walled concrete-filled steel tubular columns and important structures.
