Alternative Approach For The Analysis Of Suspended Slab Panels Under Partition Wall Load

Analysis techniques for most structural elements with different arrangement of externallyrnapplied loads are well developed and sufficiently covered with modern analysis theories.rnFurther more, the application of today’s high-speed computers enables the analysis ofrncomplex structures with different load arrangements. In addition to these effective analysisrntools, building design codes provide table of values and analysis charts for the analysis ofrndifferent elements of structural systems. As one of the structural element in buildingrnstructure, different analysis methods were proposed for the analysis of suspended slab panelrnsubjected to non-uniform loads.rnAmong the possible arrangement of externally applied loads on suspended slab panel a linernload is the one which can best represent the weight of partition wall on it. Different simplifiedrnanalysis methods were proposed to consider the contribution of this load to the design actionrneffects. The current practice of accounting this partition wall loads in the analysis ofrnsuspended slab panel is to change it to the 'equivalent' uniformly distributed load. Thernanalysis of regular slab panel subjected to uniformly distributed load may be carried out usingrncomputer softwares or using coefficients which are presented in many design codes (includingrnthe Ethiopian Building Code of Standards for concrete structures, EBCS 2 – 1995). ThernSwedish method and Reynolds method can be referred as some of the examples which arernused to obtain equivalent uniformly distributed load. These methods analysis need to berninvestigated whether they can represent the actual load or not.rnTherefore, as it is important to address this problem, comparative analysis has been carriedrnout. A new simplified method which considers the actual scenario has been developed. Thisrnnewly proposed method makes use of coefficients derived from the basic principle of elasticrnanalysis of plate. The results have been verified by comparing it with results of the finiternelement analysis. It enables us to make elastic analysis of suspended slab panel subjected tornthe weight of partition wall and avoids the uncertain use of approximate methods.
