【摘要】 随着近年来《混凝土结构设计规范》(GB 50010)的颁布实施,高强钢筋在建筑工程中逐渐得到应用。高强钢筋使用不当时,可导致混凝土裂缝宽度过大、构件挠度不易控制等问题。钢筋的加工与连接技术在高强钢筋应用中非常重要。对国内外高强钢筋的发展与应用情况进行了较为全面的介绍,对高强钢筋的材料特性进行了详细分析。根据结构构件的受力特点,通过综合考虑裂缝控制、抗震构造、施工方便、用钢量与工程造价等因素,对楼板、次梁、框架梁、框架柱、剪力墙及基础等各类常用构件中钢筋应用的特点进行讨论,给出了各种常用构件的高强钢筋应用方式建议。更多还原

【Abstract】 Since the code for design of concrete structures( GB 50010) has been promulgated and implemented resent years,the high strength reinforcement is gradually applied in the construction projects. The problems that concrete crack width is too large and component deflection is difficult to control will happen when high strength reinforcement is not properly used. Manufacture and connecting technology is very important in the application of high strength reinforcement. The development and application of high strength reinforcement were introduced and high strength reinforcement were discussed in the paper. According to the mechanical characteristics of the structural member as well as crack control,structural detailing,convenient construction, steel tonnage and the project cost ect.,the reinforcement applications for commonly used components such as slab,secondary beam,frame beam,frame column,shear wall,and foundation were discussed. The recommendations for highstrength reinforcement in commonly used components were proposed.更多还原
