Walls.-Concrete junction piers for slab walls are made of the cross-section shown to allow either single or double walling to be connected between the ribs at any angle. They may have a longitudinal hole 5, metal reinforcement 4, and grooves 7 for cement. The connection is made by ...
Solid concrete- and open framework piers are compared, in terms of stability, thermal properties and flow characteristics and building structures in terms of construction issues. FE and CFD analysis are used to give qualitative insight in the differences between the alternatives. The preferred ...
In order to provide a stable footing for such posts and to prevent moisture, frost heave and other forces from displacing them, the posts are typically installed on concrete pads or piers which are set into the ground, often to a considerable depth in order to bear the load and resist ...
The seemingly random shapes, angles and positions of the steel plates are based on a large number of deliberations and calculations by dongqi Design and structural engineers. The concrete piers look like rough rocks from the outside. The “rock” seems to have been split by a knife in order...
Edited by Michael Forsyth, this book provides essential information on the properties of the principal traditional external building materials - stone, brickwork, lime products, concrete, iron and steel, timber, wattle and daub, and glass - and their conservation. Their availability, sourcing and env...
The foundations of high-rise buildings must sometimes support very heavy gravity loads, and they usually consist ofconcretepiers, piles, or caissons that are sunk into the ground. Beds of solid rock are the most desirable base, but ways have been found to distribute loads evenly even on relat...

With the girders, beams or arches in place, the deck is paved to create the driving surface. Here, a choice between asphalt and concrete must be made, often based on local climate conditions and maintenance considerations. Concurrently, barriers are erected for safety, and utilities are installed...
Steel piers are fixed to concrete footings supported by the ground. These piers extend upward from the footings to support the girders of the frame of a house. The piers are adjustable in height so that they may be set to support the girders at proper distance above the ground. Each pier...
Because it provided more freedom in shaping structures, concrete helped the Romans develop the arch into one of the great basic construction forms. Prior to the arch, all builders in stone had been handicapped by the stone’s fundamental lack of tensile strength—that is, its tendency to break...
