Concentrating on the additional strength mannered null one

摘要

PROBLEM TO BE SOLVED: To construct a reinforcing bar joint capable of exhibiting enough strength in an earthquake with an inexpensive material in a short time and easily.;SOLUTION: In this reinforcing method for the reinforced concrete member 4, 5 in which a lap joint part of reinforcing bars 1, 2 concentrated on one section are surrounded with a steel plate 3, the diameter-thickness ratio of the steel plate is 179 or less, the length of the lap joint part is set so that the toughness rate of the reinforced concrete member is 10 or more, and the axial length of the member surrounded with the steel member is equal to or larger than the total length of the lap joint part added with the length of the covering depth from the concrete surface to a main reinforcement bar forming the lap joint at the both ends of the lap joint part.;COPYRIGHT: (C)2003,JPO
