摘要

In the construction of high-rise buildings, large span structures and tall structures, the combinatorial design structure of high strength concrete, steel fiber concrete, prestressed tendon and ordinary steel bar is a main measure to bring the advantages of high strength concrete into full play. This paper studies the nonlinear constitutive relations of high strength concrete, steel fiber concrete and steel bar. By using finite element method, this paper carries out a numerical simulation of the whole monotonic loading process of box prestressed continuous beam of high strength concrete - steel fiber concrete and gets comparatively detailedc calculating results, which provide a theoretical reference for the reasonable combinatorial design of high strength concrete, steel fiber concrete, prestressed tendon and ordinary steel bar.

7. Mechanical properties of various concrete after high temperature exposure Mechanical property of various types of concrete after high temperature exposure is investigated. Considering compressive strength requirement for a vertical element in high rise building, concrete specimens with various design strengths of 35, 80, 100, and 150 MPa were tested. Particularly, the influence of incorporated steel fiber on fire resistance is of interest in this study. Experimental results show that the fire resistance depends on the design strength and steel fiber content. Normal strength concrete (NSC) of a design strength of 35 MPa or high performance concrete (HPC) of 80-100 MPa does not spall when exposed to 100-400 °C of temperature. However, an explosive spalling occurs at 300 °C when the HPCs contain 1 vol. of steel fiber. Ultra-high performance concrete (UHPC) of a design strength of 150 MPa and 1.5 vol. of steel fiber also shows dramatic spalling at 300 °C. The experimental results found in this study can contribute to a better understanding of the behaviors of HPC and UHPC under fire and the role of steel fiber on the fire resistance. [O] . 2017
