鉄骨鉄筋コンクリート構造柱脚部の応力伝達機構に関する研究 (その1)

Abstract

To investigate stress transfer mechanism of base plate of composite columns with base; 13specimens were tested under monotonic and reversed loading. Experimental variable was chosenfor the amount of main reinforcement, applied axial load and with or without anchor bolts at base.Main discussion was concentrated on deformability, strain distribution of base plate and mainreinforcement and the failure mechanism.From the test results, it was showed that flexural strength of steel member was developed byproviding concrete and main reinforcement which restrains rotation of base plate and rising of con-crete. Also, the analytical model was formulated to estimate the strength of the test specimens andcomparisons were made between the calculated and experimental values.
