REINFORCED CONCRETE SLABS IN FIRE: EXPERIMENTAL INVESTIGATIONS ON REINFORCEMENT MESH ORIENTATION

摘要

This paper describes two series of tests carried out on slab elements with variable reinforcement mesh orientation under both ambient and elevated temperature conditions.A four-point bending was imposed up to failure of the 16 such specimens.The test results will provide useful experimental data for validating future models that are usually based on some specific assumptions.Among the tests, failure bending moment of slabs reinforced by steel bars arranged along the longitudinal and orthogonal axes of the specimen is compared with value predicted by an approach based on the yield-design theory.
