钢纤维高强混凝土承台承载力影响因素试验研究
Experimental study on factors of impacts on bearing capacity of steel fiber reinforced high strength concrete pile cap
摘要
Abstract
Based on the test of bearing behavior made on 17 specimens of steel fiber reinforced high strength concrete four-pile cape with the plane dimension of 700 mm×700 mm and thicknesses varied from 150 mm to 400 mm, the impacts from the concrete strength, volume fraction of steel fiber, type of steel fiber, effective thickness and reinforcement ratio of pile cap, etc. On the cracking load and ultimate bearing capacity of the cape are studied herein. The study result shows that the bearing capacity of the pile cape can be significantly improved along with the increases of the volume fraction of steel fiber, effective thickness of pile cap, concrete strength and reinforcement ratio of the pile cap, while the type of steel fiber has a certain impact on the bearing capacity of the pile cap as well; and then, the impacts from all the factors mentioned above must be fully considered, when establishing a formula for the calculation on the bearing capacity of the pile cap concerned.关键词
