在现行《钢筋混凝土结构设计规范》(TJ10-74) 中,由于受当时条件的限制,只列出受弯构件刚度的验算公式和受弯构件及轴心受拉构件裂缝验算公式。从1974年以来,由中国建筑科学研究院组织了规范专题的科学研究工作,有计划、有步骤地完成了两批专题,积累了大量的数据和资料,包括刚度和裂缝研究资料。这给修订新规范提供了较可靠的科学依据。从有关方面对修改规范提出的希望来
In the current “Code for Design of Reinforced Concrete Structures” (TJ10-74), due to the constraints of the prevailing conditions, only the formulae for checking the stiffness of the flexural members and the formulae for checking the cracks of the flexural members and the axial tension members are listed. Since 1974, the China Academy of Building Research organized a scientific research project on thematic topics, completed two batches of topics in a planned and systematic manner, and accumulated a large amount of data and data, including research data on stiffness and cracks. This provides a more reliable scientific basis for the revision of the new specification. From the perspective of the parties concerned on the modification of the specification
