【 摘 要 】

This study focuses on the load and resistance factor design (LRFD) procedure for anisotropic long composite cylinders under external pressure. The theoretical analysis is performed, the performance function is presented, the target reliability levels are determined, the statistical characteristics of random variables are researched and the LRFD-based code is calibrated. The results show the LRFD-based design procedure provides explicit and consistent reliability for long composite cylinder, which could lead less conservative design.
