| Research Abstract |
Shear cracks often occurs and the strength deteriorates abruptly in reinforced concrete (RC) columns and steel reinforced concrete (SRC) columns subjected to earthquake force, and buildings are damaged severely. In this studyon ultimate shear strength and collapse behavior of RC and SRC members, obtained resultsare as follows:
1) Ultimate shear strength formulae and collapse shear strength formulae was proposed by assuming shear collapsemechanism, different from the present shear strength formulae.
2) Shear failure test of RC and SRC columns was performed, and the validity of proposed formulae was testified.
3) Plastic hinges of main reinforcedbars and the steel due to dowel action was assumed, and the distance between plastic hinges were investigated.
