There are several reasons why a structure may be moved. For example, a redevelopment, such as urban regeneration, could cause a relocation.The buyer of a building may wish to move it to a new location, or the owner might sell the land that the building is on while keeping the building.
It is a rigid type of support or connection. The application of the fixed support is beneficial when we can only use single support, and people most widely used this type as the only support for a cantilever. [7] They are common in beam-to-column connections of moment-resisting steel frames and beam, column and slab connections in concrete frames.
The beam and base method of underpinning is a more technically advanced adaptation of traditional mass concrete underpinning. A reinforced concrete beam is constructed below, above or in replacement of the existing footing. The beam then transfers the load of the building to mass concrete bases, which are constructed at designed strategic ...
Also, other structural practices were added to later buildings, such as placing horizontal bond beams to transfer structural loads to the adobe roof. The extension of vigas some feet outside of the wall is a standard practice. This was used for the creation of portales or covered porches.
A Lally column is a round or square thin-walled structural steel column filled with concrete, [1] and oriented vertically to provide support to beams or timbers stretching over long spans. Lally columns are an engineered component and as such must be installed exactly as the design engineer specified.
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: 8–14 days.
Diagonal bracing is used to prevent "racking", or movement of structural vertical beams or posts. [14] Originally, German (and other) master carpenters would peg the joints with allowance of about 1 inch (25 mm), enough room for the wood to move as it 'seasoned', then cut the pegs, and drive the beam home fully into its socket.

LVL is a type of structural composite lumber, comparable to glued laminated timber (glulam) but with a higher allowable stress. [1] A high performance more sustainable alternative to lumber, Laminated Veneer Lumber (LVL) beams, headers and columns are used in structural applications to carry heavy loads with minimum weight.
