The loads applied to the beam result in reaction forces at the beam's support points. The total effect of all the forces acting on the beam is to produce shear forces and bending moments within the beam, that in turn induce internal stresses, strains and deflections of the beam. Beams are characterized by their manner of support, profile (shape ...
While plywood is the conventional material used in wood (timber) shear walls, advances in technology and modern building methods have produced prefabricated options such as sheet steel and steel-backed shear panels used for narrow walls bracketing an opening that have proven to provide stronger seismic resistance.
A stiffer beam (high modulus of elasticity and/or one of higher second moment of area) creates less deflection. Mathematical methods for determining the beam forces (internal forces of the beam and the forces that are imposed on the beam support) include the "moment distribution method", the force or flexibility method and the direct stiffness ...
Hurricane ties are in place at the top of the wall as the roof trusses are being placed. A hurricane tie (also known as hurricane clip or strip) is used to help make a structure (specifically wooden structures) more resistant to high winds (such as in hurricanes), resisting uplift, racking, overturning, and sliding.

Stirrup sample. Stirrups form the outer part of a rebar cage. The function of stirrups (often referred to as 'reinforcing steel links' and 'shear links') is threefold: to give the main reinforcement bars structure, to maintain a correct level of concrete cover, and to maintain an equal transferance of force throughout the supporting elements.

In structural engineering, a rigid frame is the load-resisting skeleton constructed with straight or curved members interconnected by predominantly rigid connections, which resist movements induced at the joints of members.
The Eiffel Tower in Paris is a historical achievement of structural engineering.. Structural engineering is a sub-discipline of civil engineering in which structural engineers are trained to design the 'bones and joints' that create the form and shape of human-made structures.
[3] Formwork for beams takes the form of a box that is supported and propped in the correct position and level. The removal time for the formwork will vary with air temperature, humidity and consequent curing rate. Typical striking times are as follows (using air temperature of 7-16 °C): Form work. Beam sides: 9–12 hours. Beam soffits: 8 ...
