Abstract

The current Japanese seismic design code on railway structures is designed to verify whether the response calculated through dynamic analysis satisfies the seismic performance required for railway structures. The seismic performance of railway structures set forth in the code was determined through experimental studies on RC members using normal-strength materials (nominal concrete strength: 50 N/mm2 maximum; nominal yield strength of the reinforcement: 390 N/mm2 maximum). Therefore, when RC members are designed with high-strength reinforcement (nominal yield strength: higher than 390 N/mm2 ) and high-strength concrete (nominal compressive strength: higher than 50 N/mm2 ), it is necessary to evaluate the seismic performance of the members and reflect this in the design. For this purpose, cyclic loading tests were performed on RC members made of high-strength materials. This paper describes the results of studies performed to verify the applicability of the current Japanese railway structure design code to RC members using high-strength materials and to identify the key points in using high-strength materials.
