STRUCTURE TO INSTALL RAILROAD PLATFORM, RAILROAD STATION INCLUDING SAME, AND DUAL-TUNED MASS DAMPING VIBRATION REDUCTION METHOD FOR RAILROAD PLATFORM

摘要

The present invention relates to a dual-tuned mass damping vibration reduction method capable of simultaneously reducing vibration, which is generated in a station structure when a train is passed, through a dual vibration reduction process or a dual-tuned mass damping vibration reduction method, and minimizing vibration in a surface member of a railroad platform. According to the present invention, a vibration reduction method of a railroad station structure using a railroad platform comprises: a process of fixing a finite element analysis model of the railroad station structure; a process of using the finite element analysis method (or a response actually measured in the railroad station structure) to calculate a spectral response at a target position of the railroad station structure so as to determine an initial design parameter; and a process of performing an optimization process calculated based on time history analysis to calculate an optimal design parameter. Moreover, a vibration reduction method of a railroad station structure using a railroad platform comprises: a process of fixing a finite element analysis model of a railroad platform installation structure; a process of calculating a spectral response in a target position in the finite element analysis method an actual railroad station structure having a structure of the finite element analysis method to determine an initial design parameter; and a process of performing an optimization process calculated based on time history analysis to calculate an optimal design parameter.;COPYRIGHT KIPO 2019
