Similar to plate girders, the SPSW system optimizes component performance by taking advantage of the post-buckling behavior of the steel infill panels. The Ritz-Carlton/JW Marriott hotel building, a part of the LA Live development in Los Angeles , California, is the first building in Los Angeles that uses an advanced steel plate shear wall ...
Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes.With better understanding of seismic demand on structures and with recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged.
The National Science Foundation (NSF) is the main United States government agency that supports fundamental research and education in all fields of earthquake engineering. In particular, it focuses on experimental, analytical and computational research on design and performance enhancement of structural systems.
Little Belt: a truss bridge in Denmark. A beam may be defined as an element in which one dimension is much greater than the other two and the applied loads are usually normal to the main axis of the element. Beams and columns are called line elements and are often represented by simple lines in structural modeling.
Lateral Queen – a pair of braced posts between a tie beam and collar beam. Prince – A strut associated with a king post truss. princess – A strut associated with a queen strut but shorter. [25] Crown – A post on a tie beam or collar beam carrying a crown plate. [26] Crown strut: A piece similar to a crown post but not carrying a plate. [27]
The top foundation layer, which formed a large plate that was in no way attached to the structure’s base, was composed of polished stones. The reason this second foundation was not tied down to the base was that in the case of an earthquake, this plate-like layer would be able to slide freely over the structure’s first foundation.
The common uses for cross bracing include bridge (side) supports, along with structural foundations. This method of construction maximizes the weight of the load a structure is able to support. It is a usual application when constructing earthquake-safe buildings. [1]
Shallow foundations of a house versus the deep foundations of a skyscraper. Foundation with pipe fixtures coming through the sleeves. In engineering, a foundation is the element of a structure which connects it to the ground or more rarely, water (as with floating structures), transferring loads from the structure to the ground.
