ABSTRACT
Composite walls are reinforced concrete walls with additional steel shapes or plates, being subjected to combined vertical and horizontal loads. Walls with additional shapes referred to as composite steel-concrete shear walls, contain one or more encased steel shapes, usually located at the ends of the wall. The design principles of composite shear walls are included in specific codes-design of composite steel and concrete structures and in provisions regarding the design of buildings for earthquake resistance. In Eurocode 8 part 7.10 are defined three types of composite structural systems: Type 1 – Steel or composite frame with concrete infill, Type 2 – Concrete walls reinforced by vertical steel sections and Type 3 – Concrete shear wall coupled by steel or composite beams. The studied walls belong to Type 2. A theoretical and experimental research program was carried out at Politehnica University of Timisoara. Six composite shear walls, scale 1:3 were analyzed and tested.
