Finite Element Modeling of RC Beam Column Sub-assemblages Subjected to Column Loss Scenario
Abstract: Progressive collapse is a situation where a failure of whole or large part of a structure occurs that has been initiated by failure of a relatively small part of the structure such as failure of any primary structural element. When a vertical load carrying element, typically a column is lost, the loads that are supposed to pass through lost column need to be safely transferred to the adjacent elements to …

Evaluation of Rutting Susceptibility of Bituminous Mixes Using Finite Element Modeling
Abstract: Pavement performance mainly depends on the quality of bituminous mixes. Poor bituminous mixes cause premature failures such as rutting or permanent deformation, cracking, bleeding etc. The design of bituminous mixes should contain certain criteria to prevent premature failures. The mixes designed based on these criteria are generally known as performance based mix design and are gaining popularity in the recent times. Among various types of pavement failures, permanent deformation or …
