A Quick Overview

This course "Design Loads considered on Bridges" explains in detail the idealization and application of various loads that are intended to act on the bridge during its design lifetime either transiently or permanently. The codal provisions related to the specification of different loads acting on the bridges are dealt with detailed information in twelve weeks sessions. Each week contains a specific load followed by the software demo session. Starting with Dead loads in the first week, the assumptions followed universally in the calculation of dead load are discussed along with sample numerically solved problems. This presentation is followed by a Staad pro demo session where a bridge structure is completely modelled and the calculated dead loads are applied. Then week two and week three presents the live load as per Indian road congress (IRC) loading and Indian Railway standards (IRS) loading.  The class A and Class B vehicular loading, Metro train, Broad gauge loading and tracked 70R loading were explained in detail with sample problems. Moving on to week four we have Earth pressure loading where the effect of soil and horizontal loading due to earth pressure were discussed in detail. Various types of Earth pressure are explained here in this week. Further week five is about wind loading in bridges. IS 875 part III codebook and its specification on wind load calculation are briefly shown here. Two staad demo sessions showing two methods of applying wind load in the bridge structure are presented. Further week 6 discusses about the various utility loads and seismic loads in the bridge superstructure. After that week seven and week eight presents the water current loads, centrifuge and impact loads as specified by the Indian roads congress. Each week has the software demo session where the corresponding load discussed in that week is applied in staad pro model and explained in step by step procedure. Then week nine deals with wave load and its effect on the bridge superstructure. Finally, weeks ten, eleven and twelve presents the temperature load, shrinkage loads, crash barrier load, hand rail loads and load combinations. All twelve-week sessions have a challenge at the end of the course which has to be completed by the student.
