CALCULATION METHOD OF DEVELOPMENT AND SPLICING LENGTH OF REINFORCING BAR

摘要

A calculation method of the anchorage and joint length of tension deformed bars is provided to apply conveniently in a construction field as compared with the anchorage and joint length of tension deformed bars which are calculated by the existing general equation, and to reduce the amount of reinforcing bars sharply. A calculation method of the anchorage and joint length of tension deformed bars comprises the steps of calculating the coating thickness by position and diameter of a reinforcing bar by satisfying the minimum coating thickness of the concrete structural drawing standards and considering the c value to be 2.5db and defining, setting the minimum bar-arrangement interval by diameter of a reinforcing bar by considering the c value to be 2.5db, calculating the distance between the center and the center by position and diameter of a reinforcing bar by applying the minimum bar-arrangement interval, and applying the c value obtained by the coating thickness and the minimum bar-arrangement interval to an equation 2 and calculating the anchorage length of tension deformed bars.
