Abstract

The building mass damper (BMD) utilizes part of a building as a tuned mass, achieving a larger mass ratio than typical TMDs, thus enhancing seismic performance. However, effective application in real buildings requires considering various factors beyond TMD theory. This paper initiates BMD design methodology by analyzing seismic response using a multi-degree-of-freedom model with stiffness and damping of the connection layer as parameters. It examines the relationship between response distribution, seismic characteristics, and TMD-derived optimal solutions. Practical design examples and BMD applicability are discussed. The CCQC method is also applied to estimate response values without analysis, evaluating its applicability.
