Strut and tie model for deep beam with openings - design and experiment

Abstract

Strut and tie model, an effective tool, has been widely recognized and applied in many countries in the world to analyze damage or design new reinforced concrete structures, especially for structures with discontinuity in geometry or load, etc. Today, this method has been introduced in many design standards such as EuroCode 2, ACI, ASSHTO, etc. and 22TCN-227-01 in Vietnam. However, these standards do not provide detailed instructions for design of deep beam with opening as well as comparisons between design and experimental results. This paper provides detailed instructions for design of deep beam with opening using strut and tie model, and then carries out experimental research to evaluate the design results.
