Abstract |
The static strengths of the existing RC beams were experimentally investigated in this paper to understand the strength characteristics of existing structural members and to get appropriate data in strengthening RC members in the remodelling construction. Ten RC beams were prepared by cutting and extracting directly from the demolition site of apartment housings and tested in order to evaluate the flexural and shear strengths of existing RC beams by their geometric condition. From the test results, it was found that most of the specimens had a sufficient structural capacity except for some special case, for example, specimens with severe cracks or concrete losses caused by improper casting. Therefore, the severely deteriorated members originated from bad concrete casting or careless construction process should be repaired and strengthened in remodelling construction.
