型钢高强混凝土的应用和发展

Application and Development of Steel Reinforced High-strength Concrete

随着现代社会的高速发展,高层建筑不断增加,各种复杂的建筑结构和异性结构也日益增多,重载、大跨、高耸是现代建筑的发展趋势,因此框架柱承受的轴向荷载也越来越大。型钢高强混凝土结构是一种新型的结构形式,它将型钢和混凝土结构有机地结合在一起,两者"优势互补",结构构件的延性(塑性变形能力)将会得到显著改善,建筑结构的整体抗震性能(抵抗地震的能力)也将得到明显提高。同时,该结构体系的正确选用,既可减轻建筑结构自身重量,还可节约钢材用量,社会效益、环境效益、经济效益等综合效益将得以凸显。因此型钢和高强混凝土的结合相得益彰,堪称完美,该结构体系必将有着更加广泛的应用和发展前景。

With the rapid development of modern society,high-rise buildings,along with various complex structures and anisotropic structures are increasingly established.Heavy load,large span and high-rise are the developmental trend of modern buildings.Therefore,the axial load of frame columns is also growing.Steel reinforced high-strength concrete,a new structural form,combines steel and concrete organically,significantly improving the ductility and seismic performance of the structure.Furthermore,the proper application of steel reinforced high-strength concrete can not only reduce the structural weight,but also saves steel.Thus economic benefits,environmental benefits and social benefits are gained.So steel reinforced high-strength concrete should be widely applied in future.
