The primary purpose of blocking is to brace longer frame members to help resist buckling under vertical compression. The intervals for the blocks are specified in the building code or as calculated by a structural engineer. Blocking also resists the rotational movement, or twisting, of floor joists as they deflect under load.
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 ...
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 ...
The wooden joinery is one of the earliest examples of modern mortise and tenon joints, [3] [4] using precisely cut notches and grooves to allow for a tight fit. This process can be repeated many times, and rise many stories, each layer of dougong joinery providing a broader, and more stable surface area for the beam. Adding multiple sets of ...

Adjustable metal screw jacks both stabilize and plumb the form Aluminum formwork system Sketch of the side view of traditional timber formwork used to form a flight of stairs Placing a wall form.

Cast-in-place concrete or Cast-in-situ concrete is a technology of construction of buildings where walls and slabs of the buildings are cast at the site in formwork. [1] This differs from precast concrete technology where slabs are cast elsewhere and then brought to the construction site and assembled. [ 2 ]
A strongback in a staircase is usually ordinary two-by dimensional lumber attached to the staircase stringers to stiffen the assembly. In shipbuilding , a strongback, known as a waler is oriented lengthwise along a ship to brace across several frames to keep the frames square and plumb. [ 1 ]
Hybrid masonry is a new type of building system that uses engineered, reinforced masonry to brace frame structures. Typically, hybrid masonry is implemented with concrete masonry panels used to brace steel frame structures. The basic concept is to attach a reinforced concrete masonry panel to a structural steel frame such that some combination ...
