1990CEB FIP模式规范(砼结构)是欧洲-国际砼委员会(CEB)批准的一个新规范.该规范是欧洲主要国家科研与工程实践的总结,与以往相比有所创新,其中砼的本构关系占有重要位置.本文从砼的多轴强度、砼的单轴和多轴应力——应变关系和特殊情况下的砼本构关系三个方面就其基本概念、原理和结论作了较详尽的介绍,可供关心这方面进展的国内读者参考.
The 1990 CEB FIP model specification (砼 structure) is a new specification approved by the European-European Commission for International Liability (CEB). This specification is a summary of research and engineering practices in major European countries. It is innovative compared to the past, in which the embarrassing constitutive relationship It occupies an important position. This article gives a more detailed introduction of its basic concepts, principles and conclusions from three aspects: the multiaxial strength of helium, the uniaxial and multiaxial stress-strain relationship of helium, and the enthalpy constitutive relationship under special circumstances. For domestic readers concerned about this progress.
