The flanged, barbell, and rectangular squat reinforced concrete (RC) walls are broadly used in low-rise commercial highway under overpasses. shear strength of is the major design consideration because their smaller aspect ratio. Most current codes or available published literature provide separate sets capacity equations for walls. Also, a substantial scatter exists predicted due to large discr...
Although studies on RC beams under shear have a history record of more than 100 years, many important issues in this context still remain that have evaded attention. The aim of the current study is to study a number of these less investigated aspects of the behavior of RC beams under shear. For this purpose, and based on the modified compression field theory, a computer program has been writte...
The seismic response of acceleration-sensitive non-structural components in buildings has attracted the attention a significant number researchers over past decade. This paper provides results which improve state-of-knowledge influences that higher vibration modes structures and nonlinearity have on floor acceleration demands. In order to study these influences, response-history analysis code-d...
Midto high-rise buildings are often braced by slender reinforced concrete (RC) walls, which are coupled by RC floor diaphragms. In design it is typically assumed that the walls act independently and the design base shear demand is computed neglecting any compatibility forces between the walls. Pushover analysis of systems comprising walls of different lengths have, however, shown that large com...
The current Eurocode 8 belongs to one of the most advanced international seismic design codes. This leading edge should be maintained in future revisions of the code while the code should become as user friendly as possible. This article makes several proposals in which way the reinforced concrete wall sections in future versions of the Eurocode can be extended in its scope but simplified in it...
Background and objective: Estimating the vulnerability rate of urban textures in seismic incident following a major earthquake (aftershocks) is crucial in decision making and crisis management. For this purpose, it is necessary to calculate the vulnerability of buildings due to the successive incidents and to use them in the vulnerability estimation for probable future aftershocks. Seismic frag...
The recent re-assessment of the seismic hazard in Europe led for many regions of low to moderate seismicity to an increase in the seismic demand. As a consequence, several modern unreinforced masonry (URM) buildings, constructed with reinforced concrete (RC) slabs that provide an efficient rigid diaphragm action, no longer satisfy the seismic design check and have been retrofitted by adding or ...
