1. 1. PARAMETRIC STUDY FOR WALL-TO-WALL CONNECTION IN MIXED STEEL CONCRETE STRUCTURES

   University essay from KTH/Bro- och stålbyggnad

   Author : Simone De Troia; [2023]
   Keywords : ;

   Abstract : The objective of this thesis work is to study the connection between two Steel Concrete Structures (SCS) wall modules using embedded connection bars. The SCSs under investigation consist of two steel faceplates held together by tie bars, concrete is cast inside, and stress transmission between the concrete and the steel plates is provided by shear connectors as headed studs.
