one important application of fiber reinforced polymer (frp) is to confine concrete as frp jackets in seismic retrofit process of reinforced concrete structures. confinement can improve concrete properties such as compressive strength and ultimate axial strain. for the safe and economic design of frp jackets, the stress-strain behavior of frp-confined concrete under monotonic and cyclic compress...

Codes for design and constructions of pressure-vessel provide a number of loading conditions that have to be considered. Pressures are primary loadings that are applied either internally or externally over the surface of the vessels; applied forces act either at local points or throughout the mass of the vessel. Among applied loads, inertial forces due to ground motion can be relevant when indu...

Design of municipal solid waste (MSW) landfills requires a considerable attention due to the undesirable environmental and socio-economical impact of a potential failure. Furthermore, recent research and engineering practice experience in developed countries characterized by high seismicity, like U.S.A and Japan, has shown that MSW landfills are vulnerable to the seismic threat. Despite the viv...

In many seismically active regions worldwide, massive reinforced concrete (RC) structures built before the 1970s existed. These older RC buildings, in countries having seismic history, were designed for gravity loads only. Anyway, beam-column connections influence where functions of connection shortage by transport forces like shear, moment, and torsion through beam to column. Also, it could be...

Study on the seismic behavior of piled rafts and pile groups while the same amount of construction material and excavation is used in their construction, are the main objective of this research. The process where the raft interaction with soil can affect the seismic response and stress distribution is also discussed in the current study. By means, ABAQUS software was applied for the finite elem...

Masonry has low cohesive strength and is susceptible to the brittle failure, when subjected to induced tensile stresses. It fails due to lateral tensile stresses even when masonry prisms are tested in uni-axial static compression and the stress-strain curve remains almost linear up to failure. Although masonry normally resists compressive forces, under lateral in-plane cyclic loads some parts o...

This article presents a research program on a structure representing a seven-story residential building tested on the shaking table in the NEES [6]. The building was designed using a displacement based capacity approach for a site in Los Angeles resulting design lateral force. The structure is composed of 2 main perpendicular walls connected by slotted connections. The numerical calculations ha...

Telecommunication tower is an important component of the basic infrastructure of communication systems and thus preserving them in events of natural disasters - such as a severe earthquake - is of high priority. In past studies, researchers have mostly considered the effects of wind and earthquake-induced loads on 3-legged (triangular cross-section) self-supporting steel telecommunication tower...

in this paper the seismic evaluation of reinforced concrete structures in petrochemical facilities under sever conditions such as high pressure, high temperature and corrosive environment is studied. these structures were designed and constructed during 1976-78. the evaluation procedure is basically performed in two phases namely; a) qualitative and b) quantitative methods. in the qualitative e...

This paper deals with the development of loading protocols appropriate for cyclic testing in regions of low to moderate seismicity in Europe. To serve this goal, cumulative damage demands imposed by a set of 60 ground motion records, representative of a European moderate seismicity region for the 2% probability of exceedance in 50 years seismic hazard level, on a wide variety of SDOF systems ar...
