because thin plate reinforced concrete members such as walls and slabs are greatly influenced by the drying shrinkage, cracks can occur in these members due to the restraint of the volume change caused by drying shrinkage. therefore, the control of cracking due to drying shrinkage is very important in building construction that the thin plate members are frequently used. however, few researches...

concrete shear walls are the most prevalent structural systems resisting lateral loads due to earthquakes in high-rise buildings. very large in-plane stiffness of shear walls provides an excellent drift control in the structure. however, structural damages and early code shortcomings threaten the efficiency of existing structural walls against earthquake. recently, fiber reinforced polymer (frp...

Strengthening of the existing seismically deficient reinforced concrete (RC) buildings is an important issue in earthquake prone regions. Addition of RC shear wall as infill or external walls into the structural system has been a commonly preferred strengthening technique since the Big Erzincan Earthquake occurred in Turkey, 1992. The newly added rigid infill walls act primarily as shear walls ...

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 ...

In tall buildings the reinforced concrete (RC) shear wall is one of the predominant structural components used to resist lateral loads induced by earthquakes around the world. Previous research demonstrated that shear walls displayed a sudden loss in lateral capacity due to the wall corner and web crushing in the plastic zone. In addition, it was found that large shear distortions in shear wall...

Unreinforced Masonry infill walls (URM) are commonly used in the Reinforced Concrete (RC) framed structures as interiors and exteriors partition walls. Although they usually are not considered in the structural analysis and design, their influence on the seismic performance of the framed structures is significant. A common practice in the modern and old RC buildings is to remove the URM walls i...

The partially prefabricated laminated (RC) walls mentioned is this kind of seismic prevention element with part prefabricated concrete plate and cast in place concrete plate. 4 typical laminated walls without openings, 4 laminated walls with openings, and 1 common cast-in-place RC walls were tested under cyclic test. The seismic behaviour were analysed by the finite element software based on th...

During an earthquake, structures are subjected to both horizontal and vertical shaking. Most structures are rather insensitive to variations in the vertical acceleration history and primary considerations are given to the impact of the horizontal shaking on the behavior of structures. In the laboratory, however, most component tests are carried out under uni-directional horizontal loading to si...
