Effects of vibrating structure on the free-field motion are presented through a field experiment at the Euro-Seistest and a corresponding numerical simulation. Ground motion has been recorded by a dense temporary three-component (3C), two-dimensional (2D) seismic network installed at increasing distances from a model building forced into vibration by pull-out tests. The building is a five-story...

This paper describes the development of a Retrievable Subsurface Accelerometer (RSA) for the NSF George E. Brown, Jr., Network for Earthquake Engineering Simulation (NEES) project at UCLA. The RSA was developed to obtain subsurface vibration data during forced-vibration experiments and aftershock events. The RSA can be rapidly installed using a CPT truck and subsequently retrieved using structu...

The uniform formulation of dynamic vibration analysis multispan beams is presented by using an efficient domain decomposition method in this paper. Firstly, the structure divided into several equal sections based on method. Next, artificial spring used to simulate complex boundaries and continuity condition beam. Finally, admissible displacement functions are expanded through Jacobi orthogonal ...
