IDEALIZATION OF STRUCTURES, FREE BODY DIAGRAM, 2 WAY SLAB, DEADLOAD AND LIVELOADS, DETERMINACY AND STABILITY OF STRUCTURE
refers to a system of connected parts used to support a load.
STRUCTURE
is the science and art of planning, designing, constructing safe and economical structures that will serve their intended purposes.
STRUCTURAL ENGINEERING
STRUCTURAL MEMBERS SUBJECTED TO A TENSILE FORCE
TIE RODS/BRACING STRUTS
ARE USUALLY STRAIGHT HORIZONTAL MEMBERS USED PRIMARILY TO CARRY VERTICAL LOADS. MEMBERS DESIGNED TO* RESIST BENDING MOMENT.*
BEAMS
MEMBERS THAT RESIST AXIAL COMPRESSIVE FORCE.
COLUMNS
CONSIST OF SLENDER ELEMENTS USUALLY ARRANGED IN A TRIANGULAR FASHION.
TRUSSES
ARE USUALLY FLEXIBLE AND CARRY THEIR LOADS IN TENSION
Cables
ACHIEVE ITS STRENGTH IN COMPRESSION, SINCE IT HAS REVERSE CURVATURE TO THE CABLE
Arches
are often used in buildings and are composed of beams and columns that are either pin or fixed connected
FRAMES
made from a material having a very small thickness compared to its other dimensions.
SURFACE STRUCTURES
is the process of determining the elements of a structure such as size of columns, beams, their reinforcements or foundation elements by methodical computation.
STRUCTURAL DESIGN
is a process of determining wether the design made can resist to actual loads; in other words. it is also to evaluate the performance of a structure.

STRUCTURAL ELEMENTS
- TIE RODS/ BRACING STRUTS
- BEAMS
- COLUMNS
is considered the backbone of all engineering programs. It deals with the basic concepts of force, moment and its effect on bodies at rest or in motion. It helps us understand how different bodies behave under the application of different kinds of loads or forces.
APPLIED MECHANICS
The Branch of Science which *deals with the study of different laws of Mechanics *as applied to the Solution of Engineering Problems is called
APPLIED MECHANICS
Mechanics can broadly be classified into two branches
- STATICS
- DYNAMICS
study of bodies at rest.
STATICS
study of bodies in motion.
DYNAMICS
are those that undergo deformation in size and shape under the effects of forces acting over them.
DEFORMABLE BODIES
Good Knowledge of _____________is essential in the study of Mechanics of Deformable Bodies.
Materials
In the Real world no solid body is ___________
______________ as everybody changes its size and shape under the effects of forces but many a times the deformation is negligible enough for the body to be considered Rigid
PERFECTLY RIGID
is any external effort or agency that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction.
FORCE
The principle states that when a force acts upon a body, it’s effect is the same whatever point in its line of action is taken as the point of application provided that the point is connected with the rest of the body in the same invariable manner.
Principle of Transmissibility of Force
The effects of two forces acting simultaneously on a body are the same as the effect of the two forces acting independently.
Principle of Superposition of Forces
A force can be represented graphically by a vector
