Plinth beam is a beam in a framed structure provided at or above (sometimes below) ground level that takes the load of the wall built on top of it. Ground beam design is done to carry the vertical loads on the beams, loads transferred from the floor slabs and loads applied by columns due to the pile eccentricities. If the grade beam is constructed above the ground level then the formwork should be similar to that conventional beam. It provides the level difference between the formations to inside floor level. shall extended minimum 50 mm beyond the width of beam on both faces. As the finish floor level of the ground floor is a kept higher than the ground level; the empty gap and void is filled with a compacted soil so as to achieve a stable surface for the floor to be constructed. In this foundation, each column has its own footing. Plinth beams are constructed at the foundation level or at ground floor level, and they are considered as tie beams at the plinth level of reducing the effective height of the columns. what is meant by plinth beam quora.

Grade beam also carries the load of the walls. 2.We should install a framework for grade beam: After the preparation and excavation is finished, it is then placed according to the dimensions of the beam. It consists of a reinforced concrete beam that transmits the load from a bearing wall into spaced foundations such as pile caps or caissons. 2. plinth. Typically the ground beams are directly rested on the ground, sometimes they can be supported by end piers. The plinth beam in a frame structure is intended to join all columns, thereby reducing the effective length and thus reducing the slenderness of the columns. Plinth beam is provided to prevent the extension or propagation of cracks from the foundation into the wall above when the foundation suffers from settlement. Do it even, not mentioned in drawings. Below wall is for holding the soil under the salb and this grade beam/plinth beam is also acting like a tie beam as it is connected from both side with pedestal of isolated footing. Actually, there is no difference between them. So it reduces the length of column and slenderness ratio. The reason to make plinth level a bit higher than the ground level is to prevent the rain or other runoff water from coming inside the building and on the other hand provide sufficient drainage to the surface water of the building. • The P.C.C. thus, the projecting part of the wall above the ground level to the floor level is the plinth.

Ground beams . Plinth beam is provided at ground level for transferring wall loads to soil. the plinth is usually kept at least 45 cm (1.5 ft) above the general ground level of the building. By digging a trench and pouring the grade beam no less than eight inches wide and to the depth equal to the span between the supports, a continuous grade beam footing will distribute the building load to the ground or to its bearing points where their bases distribute the load to the soil. A "ground beam" refers to a "grade beam", a beam that typically spans poor soil conditions to connect two or more other foundation elements to support a slab or walls that would otherwise not be supportable by the soil. Ground beams, on the other hand, are constructed at the foundation level. Actually, there is no difference between them.
