Toppling failure-> long thin rock columns formed by the steeply dipping discontinuities may rotate about a pivot point located at the lowest corner of the block; the sum of the moments causing toppling of a block (i.e. horizontal weight component of the block and the sum of the driving forces from adjacent blocks behind the block under ...
Insulating concrete form or insulated concrete form (ICF) is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs. The forms are interlocking modular units that are dry-stacked (without mortar) and filled with ...
Their study estimates the number of blocks used in construction was between 2 and 2.8 million (an average of 2.4 million), but settles on a reduced finished total of 2 million after subtracting the estimated volume of the hollow spaces of the chambers and galleries. [42] Most sources agree on this number of blocks somewhere above 2.3 million. [43]
Tilt up. A finished tilt-up building. Tilt-up, tilt-slab or tilt-wall is a type of building and a construction technique using concrete. Though it is a cost-effective technique with a shorter completion time, [1] poor performance in earthquakes has mandated significant seismic retrofit requirements in older buildings. [2]
A diagram of a mechanically stabilized earth wall as it would be modeled in a finite element analysis. Mechanically stabilized earth (MSE or reinforced soil) is soil constructed with artificial reinforcing. It can be used for retaining walls, bridge abutments, seawalls, and dikes. [1][2] Although the basic principles of MSE have been used ...
Shear wall. A typical timber shear wall consists of braced panels in the wall line, constructed using structural plywood sheathing, specific nailing at the edges, and supporting framing. A shear wall is an element of a structurally engineered system that is designed to resist in- plane lateral forces, typically wind and seismic loads.
Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is placed into a form that may be in continuous motion horizontally, or incrementally raised vertically. In horizontal construction, such as roadways and curbs, the weight of the concrete, forms, and any associated machinery ...
Masonry is the craft of building a structure with brick, stone, or similar material, including mortar plastering which are often laid in, bound, and pasted together by mortar. The term masonry can also refer to the building units (stone, brick, etc.) themselves. The common materials of masonry construction are bricks and building stone, rocks ...
