limitations in the design method used for the support systems of urban buildings make them vulnerable to damage by adjacent excavations. this paper examines a traditional system used to support excavation sites and adjacent buildings in which inclined struts are connected to the wall or foundation of the adjacent building. this method can be considered to be a type of shoring or underpinning. t...

On the basis of test results nine steel-fiber high-strength concrete corbel specimens subjected to a vertical load, influence steel fiber content on shear performance corbels was analyzed. The softened strut-and-tie model (SSTM) used analyze strength corbels, taking into consideration contribution fibers. A calculation for is proposed, and database 26 created by using model. obtained according ...

Strut and tie models consist of axial force members which react on one another and on external supports through nodes, i.e. they are trusses. An analysis of a truss problem is normally entered by reducing it to a line diagram of member centrelines representing the lines along which the stress resultants in the members are intended to act. When forces are concentrated in a line diagram the nodes...
