SUBJECT ON INTENSE VERTICAL COMPONENT OF EARTHQUAKE GROUND MOTION EXCEEDING THE GRAVITY ACCELERATION

The Effect of Vertical Component of Earthquake on Continuous and Monolithic Frame Bridges

Performance of structures during recent earthquakes shows that the effect of vertical component of earthquake (VCE) could be considered as one of the main causes of bridges collapse. In most of bridge design codes, for seismic analysis of bridges, VCE is not taken into account or a distinguished method isn’t presented for assessment of VCE. In the present work, the effect of VCE on two existing...

The Effect of Foot Orthosis on the Vertical Component of the Ground Reaction Force While Walking: A Review Study

Objective: Every person is required to walk and stand for long periods of time during daily activities, especially at work, as a result of which ground reaction force to the parts and joints is very high, and these forces sometimes reach several times the body weight in the foot and the ankle foot can have devastating effects. Various studies have suggested different methods and factors for red...

Variations of Strong Earthquake Ground Motion In

Accelerograms recorded at six stations in the metropolitan Los Angeles area during the Borrego Mountain, 1968, the Lytle Creek, 1970, and the San Fernando, 1971, earthquakes in southern California have been studied. In comparing the ground motions recorded during different earthquakes at each of the six stations and in correlations of these motions recorded at different stations during the same...

On Earthquake Ground Motion and Structural Response inAlluvial

This paper is concerned with the problem of soil ampliication and structural damage due to local site conditions in sedimentary valleys during earthquakes. It focuses on a small valley in Kirovakan, for which one dimensional (1D) wave propagation analyses have failed to provide adequate answers for the large extent and spatial distribution of damage during the 1988 Armenia Earthquake. A more re...
