: Buildings designed primarily for gravity load (GLD) are prone to suffer shear failures in walls, columns and beams when subjected to far field effects of earthquake. In previous studies, the pushover analyses on such buildings were terminated when a local shear failure occurred whereas, this study detects the shear failures and simulates the post...

... order to be compared with the demand curves, the capacity curves are converted into the Spectral acceleration-Spectral displacement (A-D) format for an equivalent single-degree-of-freedom (SDOF) system. Figure 8 presents the ultimate capacity curve of the structure obtained with and without the shear hinge. It demonstrates that the capacity would be hugely underestimated when first local shear strength capacity is considered as the ultimate capacity. Figure 9(a) depicts the stepwise base shear in the building showing the shear strength capacity attainment at different components with respect to analysis steps. Figure 9(b) present three detectable distinct stages in local shear strength capacity attainment behavior of the structure. ...

On May 21, 2021, at 21:48 local time, an earthquake with a moment magnitude of 6.1 occurred in Yangbi County, Yunnan Province, China. By using the robust strong ground motion data released by the Yunnan Earthquake Agency, we selected five near-field stations (R < 100 km) and determined model parameters, such as the duration, spectral attenuation, s...
In recent years seismic isolation technologies in Armenia were extensively applied in construction of multi-story buildings. These are 10-18-story base isolated residential complexes “Our Yard”, “Cascade”, “Arami”, “Dzorap”, “Northern Ray” and “Baghramian” designed in 2004-2008 with parking floors and with floors envisaged for offices, shopping cen...
Along with the commonly-considered earthquake excitation of the horizontal
earthquake motion, the vertical earthquake motion is of critical consideration,
particularly for high-rise structures. Many field-reconnaissance after the destructive
earthquakes with higher ratio of vertical-to-horizontal (V/H) peak acceleration proved
that the vertical ear...
This paper discusses behaviour of archetypical reinforced concrete (RC) buildings on sloping ground with two possible types of column base fixity conditions. Twisting behaviour due to stiffness irregularity is a major concern for such buildings. This study demonstrates the use of RC walls to minimise torsional effects using results of modal analysi...
In Vietnam, the load induced by earthquake had not been considered in the structure design until 2006, when the Code Design of Structures for Earthquake Resistances was first issued. However, this Code is prepared only for the building design. Hence, there still exists the quest regarding the importance of seismic load in the design of Port Structu...
