COMPARATIVE ANALYSIS OF CONVENTIONAL TRUSS SYSTEM AND CELLULAR BEAM SYSTEM

Civil Engineering

The conventional roof truss system is time consuming for construction also difficult for maintenance and a huge vertical space is made idle in truss geometry, it is combustion for utility services as well. Use of castellated beam for various structures rapidly gaining appeal, this is due to increased depth of section without any additional weight, high strength to weight ratio, their lower maintenance and painting cost. The principle advantage of castellated beam is increase in vertical bending stiffness, ease of service provision and attractive appearance. The study is related to the comparison between conventional truss system and the cellular beam system and which system is better in economy as well as suitable for the structure is find out. Economy is the main objective of this study involving comparative study carried out between conventional Howe truss and different cellular beam systems which can be design and analyzed by using SAP2000 Software. This study is carried out to determine the percentage economy and the percentage weight achieved by cellular beam system over conventional truss system. For the analysis shed having length 44m and spans 10m, 15m and 20m has been taken. The study reveals that the spine cellular beams are significantly better in economy as compared to conventional truss system.
