Abstract
There are numerous cases where a LTA (local thin area) has found near a piping branch in-service. Because the stress concentration at a piping branch intersection under internal pressure is always larger than that of a straight pipe, it is strongly necessity to establish a quantitative and reasonable plastic collapse assessment procedure. In this paper, a new assessment procedure for a piping branch with a LTA was proposed. The proposed assessment procedure was verified by the comparison of the FEA.
