TENACITY REINFORCING MECHANISM FOR COLUMN/BEAM JOINTING SECTION IN COMBINED STRUCTURE CONSISTING OF RC COLUMN AND STEEL FRAME BEAM

摘要

PURPOSE:To contrive tenacity reinforcing by placing concrete at crossed sections, after plane-crossed-frame-shaped band plates having the level of almost floor slab thickness are firmly fitted on the upper and lower respective flanges of beams at the crossed sections of the steel frame beams and RC columns. CONSTITUTION:Sections between the confronted sides of the frame pieces 3 of a closed type having the level of almost slab thickness are formed with band plates B connected to each other with reinforcing plates 4. After that, on the upper and lower respective flanges 1, 2 of beams A at the crossed positions of the steel frame beams 4 and RC columns D, the plates B and ribs 5 are fitted, and they are integrally formed. After that, hoops 7 are arranged between the webs 6 of the beams A, and after that, on column reinforcements 9 projected to the upper ends of the columns D, the reinforcements 7 and the plates B are fitted. Then, the concrete E of the fitted-on sections of slabs and columns is placed at the same time. As a result, the yield strength and tenacity of the jointed sections are increased, and the crack of the concrete, bearing pressure destruction, and joint separation between the jointed sections can be prevented from being generated.
