Abstract

Abstract

Since the properties of UHPC is different from ordinary concrete, it is inappropriate to simply adopt the design methods for concrete structures and it needs to be investigated in detail. In this paper, based on strip method, the analysis model of section bending moment and curvature was established and the related calculation program was compiled by MATLAB software. By comparing with the test data, the applicability of the calculation program was verified, and the parameters were extended, including the reinforcement rate, UHPC proportion and filling part. It was found that a portion of UHPC was recommended to be configured in both the compressive and tensile zones of the cross-section at moderate reinforcement rates. In the case of high reinforcement ratio, the full-section UHPC scheme should be used as far as possible to ensure the ductility of components. The conclusion provides a reference for section optimization configuration of flexural members.
- ultra-high performance concrete,
- high-strength steel bars,
- finite strip analysis,
- section optimization
