Abstract

A new tuned liquid damper (TLD) device – TLD embedded a transverse cylinder (TLDETC) is presented for the first time to obtain greater sloshing force and more excellent dynamic characteristics in a TLD device. The sloshing mass, sloshing force, sloshing damping ratio and sloshing frequency of a TLDETC are deduced by using fluid mechanics principle and energy method, then the comparison analysis of dynamic characteristics of TLDETC and ordinary TLD are made through three setting schemes. Deduced results show that the sloshing mass is effectively increased in TLDETC; while the analysis indicates that the dynamic performance of TLDETC outperforms that of ordinary TLD.

Key words

tuned liquid damper / TLD embedded a transverse cylinder / sloshing mass / sloshing force / dynamic characteristics
