The simplified progressive collapse method is codified in the IACS Common Structural Rules (CSR) to calculate ultimate strength of ship hull girders longitudinal bending. Several benchmark studies have demonstrated uncertainty this method, which primarily attributed variation load-shortening curve (LSC) local structural components adopted by different participants. Quantifying computational wil...

Loading margin is a fundamental measure of proximity to voltage collapse. Linear and quadratic estimates to the variation of the loading margin with respect to any system parameter or control are derived. Tests with a 118 bus system indicate that the estimates accurately predict the quantitative effect on the loading margin of altering the system loading, reactive power support, wheeling, load ...

Load shedding is generally regarded as the final option to evade voltage collapse and blackout following major overloads. The traditional method of load curtails random loads regardless their importance until system’s improved. Shedding without considering priority will lead power interruption in vital infrastructures. Hence, improve existing system protection scheme, development a more effecti...

This paper presents a methodology to assess the extent of damage to a multi-storey structure due to localised collapse. This is accomplished through the design of an algorithm, to track progressive collapse in a structure, and its implementation as a computer program. This program is based on the alternative path method of analysis, and involves systematically removing individual elements from ...
