Reliability-based load and resistance factor design(LRFD)guidelines for hull girder bending

摘要

Future guidelines for ship hull girder design will be developed using reliability methods, which can be expressed in a special format such as the Load and Resistance Factor Design(LRFD)format. The main objective of this paper is to summarize the development methodology and results of reliability-based guidelines(i.e., :RFD guidelines)for ship structures that were performed for the U.S. Navy and other government agencies. The methodology for developing the LRFD format for ship hull girder bending used in this paper consists of the following steps:(1)Probabilistic characteristics of basic strength and load random variables that are used in structural design were analyzed.
