| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程系 === 93 === This study presents an experimental investigation of reinforced concrete deep beams subjected to vertical loads. Fifteen specimens were tested to study the effects on ultimate shear strengths of deep beams of shear span-to-effective depth ratio (a/d), horizontal shear reinforcement (Ah) and vertical shear reinforcement ( ). Test results indicate that Mattock’s proposals【3】 are overly conservative for design of deep beams, especially for deep beams with fewer shear reinforcement. The ultimate shear strengths of deep beams calculated using the provisions contained in Appendix A of ACI318-02【2】are still quite conservative. Test results also indicate that the design recommendations proposed by Hwang and Lee【1】can more accurately predict the shear strengths of reinforced high-strength concrete and normal-strength concrete deep beams.
