FLAT SLAB-COLUMN JOINT PART IN REINFORCED CONCRETE STRUCTURE

摘要

PURPOSE: To improve the strength of a flat slab-column joint part so as to omit earthquake resisting elements such as an earthquake resisting wall and a brace, and a capital part. ;CONSTITUTION: In the flat slab-column joint part of a reinforced concrete structure with a column jointed to a flat slab, a slab part 10 extended around a column 20 from the column 20 is formed of high strength concrete into plate shape. Reinforcements 10c are horizontally disposed at the upper part and lower part in the slab part 10, and prestressing wires 10b are disposed between the reinforcements in the upper part and the lower part. The slab part 10 is formed in a range not longer than the shorter length between the length three times longer than the width of the column 20 and the quarter length of the total length of the left and right spans, and the slab part 10 is precast.;COPYRIGHT: (C)1996,JPO
