前言局部承压是土建工程中常见的受力形式之一,如承重结构的支座,预应力结构的锚固区,装配式柱子接头,刚架式拱结构的铰支承等等均属局部承压受力形式。以往我国在混凝土局部承压方面的实验数据比较少。工程实践中,因局部承压区混凝土开裂或强度不足而引起的质量事故也屡有发生。为此我们根据钢筋混凝土结构设计规范第二批科研专题计划的要求,开展了"钢筋混凝土及预应力混凝土构件局部承压
Foreword Partial pressure is one of the common forms of stress in civil engineering. For example, the bearing of bearing structure, the anchorage zone of prestressed structure, the joint of assembled pillar, the hinged support of rigid frame arch structure, etc. Forced form. In the past, there were few experimental data on local concrete pressure in concrete. In engineering practice, quality accidents caused by concrete cracking or insufficient strength in the partial pressure zone also occur frequently. For this reason, according to the requirements of the second batch of scientific research special projects for the design specification of reinforced concrete structures, we have carried out a partial pressure-reinforcement of reinforced concrete and prestressed concrete components.
