Abstract
The infrastructure should be design in such a way that ensures safe, serviceable, durable and economic construction. For the beam design, the joints between beam and column is traditionally considered a rigid connection which actually not fully rigid and therefore accounted an extra moment leading to structural over-design and subsequently higher cost of beam construction. This paper proposed a theoretical model for moment and deflection considering the actual stiffness of beam-column joint rather than traditional concept of rigid connection. A concentrated moving load is applied on the beam with three different support conditions such as fixed both end, simply supported and propped cantilever. This proposed model is then verified theoretically considering known boundary conditions. Results showed that the proposed theoretical model for moment and deflection of beam perfectly captured the existing beam equations with that specific support conditions and the cost of the beam construction can be reduced due to considering the actual beam-column joint stiffness.
