RCC Box Culvert, WSM & LSM


As per standard practice bridges (Short Span less than 6M) were designed by IRC: 6 – 2000 & IRC: 21 – 2000. Both the codes were based upon Working Stress Method. But IRC has revised IRC: 6 – 2000 as IRC: 6 – 2014 and published a new code IRC: 112 - 2011 for bridges design. These are based upon the Limit State Method. In the present study using these codes a RCC Box Culvert of 4M span & height is analyzed & designed with WSM approach as well as LSM approach. A MS – Excel sheet is also developed by manual calculation for the same. Results of manual analysis, MS – Excel sheet & Staad Pro are compared for design the problem The Design based on both the approaches WSM & LSM are also compared & a parametric study is carried out by keeping Steel Grade as constant with different Grade of Concrete and finding the % reduction in Steel Reinforcement as well as % reduction in section dimensions due to LSM approach over WSM approach. This study will eventually comment on the design philosophy LSM & WSM regarding the design of RCC Box Culvert and discussed which one will perform better economically as well as structurally. The developed MS – Excel tool is user friendly, error free & fast for convenient-application for the RCC Box Culvert Design
