First draft of performance-based design code for Japanese protective structures

摘要

This chapter introduces a commission report on the performance-based design concept for protective structures under an impact load by subcommittee activities of the Japan Society of Civil Engineers.Although definite prescription and procedure of design are not involved,fundamental philosophy on the performance design for structures under an impact load is discussed.In addition,several important points to notice on the evaluation of structural per-formance by numerical analysis or impact experiment are indicated.From these initial trials,JSCE committee will continue to revise them and improve their degree of completion.
