Building Construction 2
Building Construction 2 : Methods are (1) Solid Construction: Walls of solid brick or stone. Cast-iron columns can be used to support either cast iron or wooden beams which are bedded in the load-bearing walls at either end. (2) Structural Steel Frame Construction: A steel frame skeleton is used to carry the weight of the floors and cladding at each level by beams which pass the loads to the columns. Non-loadbearing cladding materials are used. (3) Reinforced Concrete Construction: Some systems still use columns, supporting main beams which in turn support the floor slabs. Later designs are of a monolithic type often called slab construction where the beams are rigidly attached to the columns and the floors are cast integrally with the beams. Variations include a) lift slab construction where the columns are progressively extended and the floor slabs are cast on site around them; and b) the cross wall and box. frame construction where not only the columns, beams and floors are cast as the building rises in height during construction but also the walls. (4) Portal Frame Construction: The concrete, steel or timber columns are rigidly connected to the structural roof members. Used for single storey structures. (5) Lightweight Steel Construction: Open web steel joists are used positioned either on structural steel framing or on loadbearing masonry walls. (6) Timber Construction: Timber used as structural framing. Heavy timber construction with masonry walls and lighter timber framing is used with panels sheathed with brick veneer, asbestos cement, wood or metal cladding. Glue laminated structural members may be used. See also: Building Industrialised, Composite Construction, and Dry Construction
