AISC's Structural Steel Shapes

Structural steel design  is an area of knowledge of structural engineering where we used to design steel structures. The structures can range from schools to homes to bridges. Structures such as buildings, bridges, aircraft and ships are all examples which comes under steel structure. 

The effects  cause on structure due to application of load is determine through structural analysis Strength of materials is the branch of engineering which deals with the study of structural design. Engineering software such as STADD Pro, TEKLA , SACS, ANSYS  etc.  are used to analyze their strength. 

Basically  Steel structure is steel construction material with a unique  profile and  a specific shape or cross section with certain standards of chemical composition and mechanical properties.

The American Institute of Steel Construction (AI SC), Inc. publishes the Steel Construction Manual (Steel construction manual, or SCM), which is currently in its 14th edition. Structural engineers use this manual in analyzing, and designing various steel structures.

The mentioned link will give you the complete description of AISC 's structural steel shapes in the US  and will provide you the reference to determine the availability and engineering design data of specific structural steel shapes.

Shear and Bending Moment diagrams

Shear and Bending Moment diagrams

Bending Moment -

It is reaction produce in a element when an external force or moment is applied to the element which causes elements to bends.

Shear Force - 

force acting parallel to the cross section of elements or acting along the plane is      called a shear force or shearing force.

Below is the Link provided for Shear Force and Bending Moment Diagram Calculation of a Beam:-

Below I am showing how to calculate shear force and bending moment diagram. you can find many link for calculating bending moment diagram for different loading and support. example i          have show  below for one condition.

Be care full about units of input data to get the correct result.

Finite Element Analysis of Composite Sandwich Panel Under Static Load condition

Definition of composite material terminology:-

composite materials:- 

A Composite material is a material made from two or more constituent materials with different physical or chemical properties .when it is combined it produces a material with characteristics different from the individual components.

Orthotropic martial:-

Orthotropic materials have material properties that differ along three mutually-orthogonal twofold axes of rotational symmetry and their properties change when measured from different directions.

Anisotropy:-

 is the property of material which depends on direction, which implies different properties in different directions, opposite to that of  isotropy. It can be defined as a difference, when measured along different axes, in a material's physical or mechanical properties.
