This document provides an introduction to steel-concrete composite structures. It explains that steel-concrete composite elements use concrete's compressive strength alongside steel's tensile strength, resulting in a highly efficient and lightweight unit commonly used for buildings and bridges. It then discusses the advantages and disadvantages of reinforced concrete structures, steel structures, and steel-concrete composite structures. Examples of existing steel-concrete composite buildings are also presented.

2. WHAT IS STEEL-CONCRETE
COMPOSITE STUCTURE ?
STEEL-CONCRETE COMPOSITE ELEMENTS
USE CONCRETE'S COMPRESSIVE
STRENGTH ALONGSIDE STEEL'S
RESISTANCE TO TENSION, AND WHEN TIED
TOGETHER THIS RESULTS IN A HIGHLY
EFFICIENT AND LIGHTWEIGHT UNIT THAT IS
COMMONLY USED FOR STRUCTURES SUCH
AS MULTI-STOREY BUILDINGS AND
BRIDGES.

3. ADVANTAGES & DISADVANTAGES OF RCC STRUCTURE
ADVANTAGES
Reinforced Cement Concrete has good
compressive stress (because of concrete).
RCC also has high tensile stress (because of
steel).
 It has good resistance to damage by fire and
weathering (because of concrete).
RCC protects steel bars from buckling and
twisting at the high temperature.
RCC prevents steel from rusting
DISADVANTAGES
The tensile strength of reinforced concrete is
about one-tenth of its compressive strength.
The main steps of using reinforced concrete
are mixing, casting, and curing. All of this affect
the final strength.
The cost of the forms used for casting is
relatively higher.
For multi-storied building the RCC column
section for is larger than steel section as the
compressive strength is lower in the case of .
Shrinkage causes crack development and
strength loss.

4. ADVANTAGES & DISADVANTAGES OF STEEL
STRUCTURE
ADVANTAGES
Lower Project Costs.
Aesthetic Appeal.
High Strength.
Sustainable.
Innovative.
Modifiable.
Efficient.
DISADVANTAGES
 Steel is an alloy of iron.
 It has high maintenance costs as it has to be
painted to make it corrosion-resistant.
 There are extensive fireproofing costs
involved as steel is not fireproof.
 Buckling is an issue with steel structures.
 Steel has a high expansion rate with
changing temperatures.

5. ADVANTAGES & DISADVANTAGES OF STEEL-CONCRETE
COMPOSITE STRUCTURE
ADVANTAGES
The concrete acts together with the steel to
create a stiffer, lighter, less expensive
structure.
Speed and simplicity of construction- faster
to erect, nearly 25% faster then traditional
construction.
Has better ductility and hence superior
lateral load behavior; better earthquake
resister.
Ability to cover large column free area in
buildings and longer span for bridges/flyovers.
DISADVANTAGES
 Provide misleading messages about quality
if poorly constructed or misinterpreted.
 Lead to simplistic policy conclusions.
 Can be misused, if the construction process
is not transparent and lacks sound statistical
or conceptual principles.
 Selection of metrics and weights can be
challenged by other stakeholders.
