Benson, Simon Derek. This thesis investigates the progressive collapse behaviour of lightweight ship hull girders including the effects of compartment level buckling modes. An extension to the progressive collapse methodology is proposed, which has capabilities to predict the compartment strength of a lightweight aluminium midship section.
PROGRESSIVE COLLAPSE, METHODS OF PREVENTION
Review on Progressive Collapse of Building Structure – IJERT
Abstract Nowadays man-made and natural hazards like terrorist attack, gas cylinder burst, fire, gas explosion, etc. Progressive collapse is the result of these manmade and natural hazards. Progressive collapse takes place when one or more columns fails, this results in failure of adjacent members and finally leads to partial or whole structure failure. In the present study, L shape 12 story reinforced concrete framed structure is considered to assess the demand capacity ratio DCR. The analysis is carried out by removing columns at different locations one at a time as per General Service Administration GSA guidelines, and then DCR values for beam and column are evaluated. The results concluded that the column removed at center is more vulnerable for progressive collapse. The buildings are first designed and then planned for ultimate forces or stresses resistance.
Review on Progressive Collapse of Building Structure
Alogla, KD , Experimental and theoretical evaluation of progressive collapse capacity of reinforced concrete framed structures , PhD thesis, University of Salford. Progressive collapse is a situation when local failure is followed by collapse of adjoining members, which in turn causes global collapse, threatening life. Local failure of a vertical load carrying member, can be caused by abnormal loading such as explosion, bombing, sudden vehicle impact and design errors.
Unreinforced masonry URM structures have shown to be susceptible to significant damage during strong earthquakes. Vulnerability assessment of URM buildings is needed so that appropriate mitigation strategies can be implemented. The existing Canadian practice consists of rapid seismic screening of buildings to assign priorities for further and more refined assessments, followed by refined analysis of individual critical buildings. Current research with respect to the protection of civilian infrastructure against complex blast loading conditions is primarily focused towards the effect of external explosive sources.
