Transcript of Structural Analysis

Structural Analysis Equilibrium Trusses Thermal Stresses Torsion Trusses are the main part in building structures and
in architecture and structural engineering, a truss is a structure comprising one or more triangular units constructed with straight members whose ends are connected at joints referred to as nodes. External forces and reactions to those forces are considered to act at the nodes and result in forces in the members which are either tensile or compressive forces. Moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes. Torsion is the twisting of an structure due to the applied torque.
Torsion acting on a long bar tends to twist it in the direction of the torque All of the members and structures that we have considered so far were assumed to remain at the same temperature while they were being loaded .we are now going to consider various situations involving changes in temperature. The Course is mainly based on equilibrium which is defined as Summation of all forces and moments equals zero ,and in case of structure analysis it means that a structure will be able to sustain all external loads ,and its internal force can handle the external pressure. Bending Hooke's Law A Law stating that, in a linear system, the restoring force is proportional to the displacement of the body, acting in a direction as to restore equilibrium. Bending is a process by which metal can be deformed by plastically deforming the material and changing its shape. The material is stressed beyond the yield strength but below the ultimate tensile strength. The surface area of the material does not change much. Bending usually refers to deformation about one axis. Our website discusses 6 main topics: These topics simplifies our course This course is...
