Steel-Concrete Composite Structures

Course Description:

Introduction to the design of structural elements comprising of two materials, namely structural steel and reinforced concrete. Analysis and dimensioning of composite members (beams, slabs, columns), ultimate and serviceability limit state checks according to the Eurocodes and specifically with Eurocode 4. Design of buildings with composite structural members.

Prerequisite Knowledge

Mechanics, Structural Analysis and Steel Structures

Course Units

# Title Description Hours
1 Introduction Buildings with composite structural elements, basic principles of the behaviour of structures with different materials: structural steel – reinforced concrete. 2
2 Structural Materials Material properties according to Eurocode 4: Structural steel – concrete – reinforcing steel – bolts – steel sheeting. 2
3 Composite Beams: Analysis and ULS design Calculation of cross-sectional properties, methods of analysis, moment resistance with plastic and elastic analysis, shear resistance, shear connection for the Ultimate Limit State. 16
4 Composite Beams: Analysis and SLS design Calculation and checks of deflections, design against cracking and vibration for beams in the Serviceability Limit State. Construction phases. Detailing. 8
5 Composite Slabs: Analysis and design Typology of composite slabs, methods of construction, ULS and SLS checks. Detailing. 8
6 Composite Columns: Analysis and design Typology of composite columns, calculation of cross-sectional properties, plastic resistances, axial force & moment interaction, buckling checks, detailing. 12
7 Fire Design Behaviour of materials of composite members under high temperatures, methods of design based on the time of exposure, the applied load or the method of construction. Simplified methods of design of composite beams, slab and columns. 4

Learning Objectives

After the successful completion of the course, students will be able to: 1. know the behaviour of members and structures of different structural materials, 2. form buildings and other structures with structural steel and reinforced concrete members 3. distinguish the methods of analysis and construction phases of such structures 4. design composite beams, slabs and columns according to Eurocode 4
