In this study, linear and non-linear static analysis of low-rise models representing two-bay two-story three-bay three-story reinforced concrete framed structures designed as per Indian standard codes (IS 450:2000 IS 1893:2016) for the high seismic region using Envelope loading combination are assessed with without Guidelines U.S. (GSA) General Services Administration. The purpose study is to d...

This paper presents dynamic voltage collapse prediction on an actual power system using support vector regression. Dynamic voltage collapse prediction is first determined based on the PTSI calculated from information in dynamic simulation output. Simulations were carried out on a practical 87 bus test system by considering load increase as the contingency. The data collected from the time domai...

The present paper deals with the experimental and computational study of axial collapse of the aluminum metallic shells having combined tube-frusta geometry between two parallel plates. Shells were having bottom two third lengths as frusta and remaining top one third lengths as tube. Shells were compressed to recognize their modes of collapse and associated energy absorption capability. An axis...

In many studies, the alternative load path method (APM) has been used for progressive collapse analysis. In this method, one or several columns of the building are removed and the building response is investigated. This method ignores the initial local failure cause of building and this can affect the structural response. Investigation of ignoring the initial local failure cause of steel braced...

Power systems form one of the largest and most complex technical systems. Changes of load parameters may lead to so called bifurcations, resulting in nonlinear phenomena like voltage collapse or interarea oscillations. Special software tools are able to simulate these systems and to identify bifurcations. This paper presents a systematic approach to determine gain factors of Flexible AC Transmi...

Outage of a heavily loaded transmission line or tripping of large generating unit may lead the system toward collapse. Under such circumstances, compared to other measures, load shedding procedure is an efficient method to make the power system voltage stable when many system variables are out of their normal ranges and the system is driven toward collapse. This paper introduces the concept of ...

To study the laws of evolution dynamic increase factors (DIFs), relationship between DIFs and progressive collapse resisting capacity a structure with web cleat joints under column removal scenario, refined finite element model is established based on an existing quasi-static test. The are studied for different loading type, beam height, joint rotation stiffness. It was observed that displaceme...
