The vertical loads, due mainly to the occupancy, self-weight and snow or rain, are commonly referred to as
(a)
consist of the weight of the various structural members and the weights of any objects that are permanently attached to the structures.
(a)
can vary both in their magnitude and location. They may be caused by the weights of the objects temporarily placed on a structure, moving vehicles, or natural forces.
(a)
In some parts of the country, roof loading due to snow and rain can be quite severe, and therefore, protection against possible failure is of primary concern.
(a)
When structures are used to retain water, soil or granular materials, the pressure developed by these loadings becomes an important criterion for their design.
(a)
When live loads are applied rapidly to a structure, they cause larger stresses than those that would be produced if the same loads would have been applied gradually. The dynamic effect of the load that causes this increase in stress in the structures is called
(a)
When structures block the flow of wind, the winds kinetic energy is converted into potential energy of pressure, which causes a wind loading. The effect of wind on a structure depends on the velocity of the air, the angle of incidence of the wind, the shape and stiffness of the structure, and the toughness of its surface.
(a)
Earthquakes produce loadings on a structure through its intersection with the ground and its response characteristics. These loadings result from structure distortion caused by the ground’s motion and the lateral resistance of the structure
(a)
is a loading that exist along the full length or longitudinal axis of a beam.
(a)
is a loading that is perpendicular to the longitudinal axis of a beam.
(a)
a force applied at a very small portion on abeam
(a)
a load that is distributed or spread across the whole region of a beam.
(a)
a load that spread over the beam which is linearly varying from one end to the other end.
(a)
allows rotation and horizontal forces but will resist vertical forces.
(a)
allows rotation but will resist horizontal forces and vertical forces
(a)
is a rigid connection that will resist all forces on the horizontal, vertical, and rotational forces.
(a)
REFERS TO A SYSTEM OF CONNECTED PARTS USED TO SUPPORT A LOAD. IMPORTANT EXAMPLES RELATED TO CIVIL ENGINEERING INCLUDE BUILDINGS, BRIDGES, AND TOWERS; AND IN OTHER BRANCHES OF ENGINEERING, SHIP AND AIRCRAFT FRAMES, TANKS, PRESSURE VESSELS, MECHANICAL SYSTEMS, AND ELECTRICAL SUPPORTING STRUCTURES ARE IMPORTANT.

STRUCTURAL ANALYSIS
IS A PROCESS OF DETERMINING WHETHER THE DESIGN MADE CAN RESIST TO ACTUAL LOADS IN OTHER WORDS, STRUCTURAL ANALYSIS IS TO EVALUATE THE PERFORMANCE OF THE STRUCTURE.

STRUCTURAL ANALYSIS
IS A STRUCTURE THAT IS STABILISED BY TENSION RATHER THAN COMPRESSION.

TENSILE STRUCTURE
PLANE TRUSS
SPACE TRUSSES,
SHEAR WALL
ON THE OTHER HAND, HAVE MEMBERS THAT ARE NOT LIMITED TO A SINGLE PLANE. THIS MEANS THAT ___ NEED TO BE ANALYZED AS A THREE-DIMENSIONAL SYSTEM.

ARE AN IMPORTANT COMPONENT OF BUILDINGS AND GENERALLY COMPRISE SEVERAL SHAFTS INTENDED TO HOUSE ELEVATORS AND STAIRS
SHAFT/CORES
FRAMING SYSTEM
BRACING SYSTEM
DIAPHRAGM
IS THE PROCESS OF CONNECTING BUILDING MATERIALS TOGETHER TO. CREATE A STRUCTURE. STUDS, PLATES, HEADERS, RAFTERS, GIRDERS, FLOORING AND JOINTS ARE ALL TERMS USED TO IDENTIFY DIFFERENT COMPONENTS IN FRAMING.

IS A STRUCTURE THAT ALTERS THE LOAD PATH OF THE GRAVITY LOADS, SHIFTING THE LINE OF THRUST LATERALLY TO A DIFFERENT VERTICAL ALIGNMENT
SUPERSTRUCTURE
SUB STRUCTURE
FOUNDATION
LOAD TRANSFER
IS THE PART OF A BUILDING THAT FIXES IT INTO THE SOIL. THESE STRUCTURES PROVIDE SUPPORT FOR THE MAIN STRUCTURES THAT APPEAR ABOVE THE SOIL LEVEL, MUCH LIKE THE ROOTS OF A TREE SUPPORT THE STEM

STRUCTURAL MEMBERS SUBJECTED TO A TENSILE FORCE ARE OFTEN REFERRED TO AS TIE RODS OR BRACING STRUTS. DUE TO THE NATURE OF THIS LOAD, THESE MEMBERS ARE RATHER SLENDER, AND ARE OFTEN CHOSEN FROM RODS, BARS, ANGLES OR CHANNELS.
TIE RODS
BEAMS
COLUMNS
TRUSSES
ARE USUALLY STRAIGHT HORIZONTAL MEMBERS USED PRIMARILY TO CARRY VERTICAL LOADS. BEAMS ARE USUALLY PRIMARILY DESIGNED TO RESIST BENDING MOMENT; HOWEVER, IF THEY ARE SHORT AND CARRY LARGE LOADS, THE INTERNAL SHEAR FORCE MAY BECOME QUITE LARGE AND THIS MAY GOVERN THEIR DESIGN. BEAM STRENGTH IS LARGER WHERE THE BEAM MOMENT IS LARGER
TIE RODS
BEAMS
COLUMNS
TRUSSES
MEMBERS THAT ARE GENERALLY VERTICAL AND RESIST AXIAL COMPRESSIVE LOADS ARE REFERRED TO AS COLUMNS. OCCASIONALLY, COLUMNS ARE SUBJECTED TO BOTH AN AXIAL LOAD AND A BENDING MOMENT AS SHOWN IN THE FIGURE CALLED BEAM COLUMN.
TIE RODS
BEAMS
COLUMNS
TRUSSES
WHEN THE SPAN OF A STRUCTURE IS REQUIRED TO BE LARGE AND ITS DEPTH IS NOT IMPORTANT CRITERION FOR DESIGN, A TRUSS MAY BE SELECTED.
