Pet Friendly Stair Railing. This sunny staircase leads to the children's room on the lower level of a California home designed by Mark D. Sikes to embrace fun inside and out. The railings and ...
Other light-frame buildings are built over a crawlspace or a basement, with wood or steel joists used to span between foundation walls, usually constructed of poured concrete or concrete blocks. Engineered components are commonly used to form floor, ceiling and roof structures in place of solid wood.
The wood-framed 5-over-1 style is popular due to its high density and relatively lower construction costs compared to steel and concrete. [9] 5-over-1 buildings often feature secure-access interior hallways with residential units on both sides, which favors a U, E, C, or right-angle building shape. [7]
This method of construction is widely used for concrete structures, but the advantages of using similar techniques with stone are only just being realised.". [4] For concrete, this problem has been long solved: in addition to conventional tensile reinforcement, engineers developed prestressed concrete methods starting around 1888. Such tension ...

Figure 4 Reinforced concrete shear wall with both horizontal and vertical reinforcement. Concrete shear walls are reinforced with both horizontal and vertical reinforcement (Figure 4). A reinforcement ratio is defined as the ratio of the gross concrete area for a section taken orthogonal to the reinforcement.
A flitch beam is a simple form of composite construction sometimes used in North American light frame construction. [3] This occurs when a steel plate is sandwiched between two wood joists and bolted together. A flitch beam can typically support heavier loads over a longer span than an all-wood beam of the same cross section.
