Experimental Formula to Determine the Natural Period of Wall-slab Apartment Building Structures |
| Abstract |
The purpose of this study is to investigate experimentally the shear behavior of high-strength reinforced concrete beams for longitudinal steel ratio subjected to monotonic loading. The shear strength of reinforced concrete beams without stirrups is dependent on the compressive strength of concrete, the longitudinal steel ratio, the shear span to depth ratio. In this study, Ten reinforced concrete beams using high strength concrete(f'c=98MPa) are tested to determine their ultimate shear capacity. The main variables are longitudinal steel ratio and shear span-depth ratio a/d = 1.0, 1.5, 2.0, 2.5, 3.0. All specimens are 125 mm wide and have a total depth of 250 mm. The effective depth is 215 mm. The test beams is simply supported at ends and loaded by one point loads. The test results were analyzed and compared with strength predicted by ACI code equation, Zsutty's equation, Bazant's equation and Shin's equation. |
