Code Provisions for High Strength Concrete Strength-Temperature Relationship at Elevated Temperatures

摘要

This paper presents results of experiments, conducted at NIST and elsewhere, to measure compressive strength of concrete at elevated temperature. The paper compares the test data with existing design rules and recommendations to assess their applicability to HSC. Based on the compiled data, the paper proposes new strengthtemperature relationship for HSC and discusses the need for standardizing the test procedure for testing concrete at high temperature and for a revision of the current design guides to include new data for properties of concrete at high temperature.
