This construction video briefly demonstrates the process for setting up footings and RCC columns essential for developing a building.
The concreting of RCC Columns, pedestals and footings should be perfect to maintain the optimal strength and stability of these structural members. Inappropriate concreting process may result in creating erosion of steel reinforcement because of pores, cracks in concrete and concrete fails to obtain its target strength on setting. This may also cause collapse of columns, pedestals or footings throughout the occupancy of the structure.
Footing consists of the lower end of a column, pillar to disperse load.
Footings are designed specifically to retain the applied loads, moments and forces and the induced reactions and to make sure that any probable settlement should be as identical as possible and soil’s safe bearing capacity is not surpassed.
In sloped or stepped footings, the operative cross-section in compression is restricted by the area over the neutral plane, and the angle of slope or depth and location of steps should be kept in a manner that the design requirements are fulfilled at each section.
