Experimental Research on Development and Splices Length in High-Strength Concrete Flexural Members
Abstract
This paper presents the test results of 24 beam-end specimens to investigate the effect of concrete strength and cover thickness on the development resistance capacity in tensile lap splice length regions. The results showed that as higher strength concrete was employed, nor only development resistance capacity was influenced by cover thickness, but also more sufficient safety factor reserved shorter than the lap splice length provision in current design code. From experimental research results, high-strength concrete development length was not inverse ratio of (
