Abstract: This paper presents the results of an experimental and analytical study of a slender monumental stair. The objective of the study was to gain insight into slender stair vibration issues and provide guidance for the design ...

Abstract: When occupants complain of lively floor motion due to human activity, it is often necessary to estimate the dynamic properties of the floor and ascertain the form and level of vibration response toward the goal of designing ...

Abstract: Extended end-plate moment connections are one alternative to fully welded connections that has been considered for use in seismic force resisting moment frames. As a part of the SAC Steel Project, a research program to ...

Abstract: Large floor vibration amplitudes can produce disruption and reduced efficiency in employees, and in more extreme cases can result in complete abandonment of a structure for its intended use. The implementation of active ...

Abstract: Finite element modeling is used to develop prediction equations characterizing the general behavior of extended stiffened end‐plate connections that can be used for heavier beams in steel building frames. Salient features ...

Abstract: This paper presents the results of a live-load test of the Shenley Bridge, the first bridge application of the sandwich plate system technology in North America. The investigation focused on the evaluation of in-service ...

Abstract: This paper presents the results of the analytical and experimental studies of a pendulum tuned mass damper (PTMD) to control excessive floor vibrations due to human movements. The PTMD used in this study acts as a passive ...

Abstract: A semiactive magnetorheological device is used in a pendulum tuned mass damper (PTMD) system to control the excessive vibrations of building floors. This device is called semiactive pendulum tuned mass damper (SAPTMD). ...

Abstract: The sandwich plate system (SPS) is a relatively new bridge deck system that consists of steel face plates bonded to a rigid polyurethane core. The decks are thin, lightweight, and modular in design and can be tailored to ...
