Concrete Grid Beam

They should be reinforced with continuous reinforcement that is developed within or beyond the supported column or be anchored within the pile cap or footings as per aci 318 14.

Concrete grid beam.

Stabilized by the grid beam system together with soil nail installation see fig. A grade beam differs from a wall footing because a grade. Section of a waffle slab including beam ribs and column head. A structural reinforced concrete continuous beams at an intermediate building floor provides gravity load resistance for the applied dead and live loads.

Wholistically it forms a structural skeleton for the building which is used to support other members such as floors roof walls and claddings. Figure1shows a typical application of continuous grid beam structure on a man made slope. Continuous grid beam structures made of concrete have been used for many years in china to stabilize the natural and man made slopes. 25 mm in diameter and 16 l ft 5 0 m long were installed to cover the target area of 5442 yd 2 4550 m.

It is used in conditions where the surface soil s load bearing capacity is less than the anticipated design loads. The dimension of the grid beam cross section was 12 x 12 in. Waffle slabs are preferred for spans greater than 40 feet as they are much stronger than flat slabs flat slabs with drop panels two way slabs one way slabs and one way joist slabs. Generally this slope stabilization structure is called grid beam.

In this type of floor a mesh or grid of beams running in both the directions is the main structure and the slab is of nominal thickness. A grade beam or grade beam footing is a component of a building s foundation. The main difference between flat slab conventional slab beam system is that the one is directly supported on the column while another system has a beam for support. At intersections of the concrete grid beams 1157 pieces of soil nail 1 in.

An assembly of intersecting beams placed at regular interval and interconnected to a slab of nominal thickness is known as grid floor or waffle floor. The load is transferred directly from slab to column in the flat slab. In conventional slab beam system the load is transferred from slab to beam and ultimately beam to the column. A waffle slab or two way joist slab is a concrete slab made of reinforced concrete with concrete ribs running in two directions on its underside.

It consists of a reinforced concrete beam that transmits the load from a bearing wall into spaced foundations such as pile caps or caissons. Concrete frame construction is a construction method which comprises a network of columns and beams to transfer the loads coming onto the structure to the foundation successfully. For example a 20 20 ft grid could have one intermediate beam so 3 ply clt floor panels spanning 10 ft can be used. The name waffle comes from the grid pattern created by the reinforcing ribs.
