A concrete corbel can fail in a few ways based upon the loading mechanism along with other factors. Such failure of a member in its service life may be catastrophic to the integrity of the overall structure. The failure mechanisms of corbels can be divided in six basic modes: bending, concrete crushing on the strut, shear at the interface between the corbel and the column, loss of anchorage of the main tie reinforcement, horizontal load, and concrete crushing under the bearin

Portal beams are usually put to use when the placement of a single pier is not feasible. This might be due to some obstruction or otherwise when the viaduct has to cross a road and the placement of a single pier would obstruct the road. These structures are either in RCC, steel, composite or designed with post tensioned beams. STRUCTURE The case we are expounding is that of a single piercap and single viaduct portal pier, which hosts tow box girder spans on either sides. Por

There are many types of piers in a typical Metro Mass Transit System anywhere. Station piers are the most critical piers that are designed for an elevated metro system in any city. A series of these piers constitute an entire metro station. Generally, these are designed as huge expanded double portals the design of which I will expound in some other article. A unique type of station pier is a singular pier with freely hanging cantilevers branching from either sides, support

Grid analysis is the fundamental aspect of bridge engineering as far as understanding any bridge span is concerned Grid analysis or grillage analysis of a span is the virtual modelling and simulation of all forms of conditions and forces upon the bridge span that can occur in its service life. The bending , shear, torsional stresses so developed within the model help us in the preliminary design of bridge girders, diaphragms, cross bracings, and decide other geometrical and
