Abstract: In this paper a new free interface modal synthesis method for the dynamic analysis of linear structures by the finite element method is developed. The technique is based on the so called ...

Abstract: This paper presents two simplified methods for calculating the seismic force coefficients for flexible nonstructural components in building structures. The methods utilize the dynamic characteristics, expressed in terms ...

Abstract: The paper examines the seismic design force formulas that are currently prescribed in the 2003 NEHRP Provision for the design of nonstructural components in buildings, and presents new formulas to improve the these ...
