Front 1

Basically most structures may be classified as beams, rigid frames or trusses or combination of these elements.

Back 1

layout and classification of structure

Front 2

deals with the principles and methods by which the direct stress, the shear and the bending moment and the deflection at any section of each constituent member in the structures may be calculated

Back 2

theory of structure

Front 3

is a combination of units constructed and so interconnected in an organized way, as to provide rigidly between its elements.

Back 3

structure

Front 4

is a structural member whose prime function is to carry transverse loads such a joist, girder, rafter or purlin. It is completely analyzed when the shear and bending moment values have been found

Back 4

beam

Front 5

is composed of members connected by rigid points ( welded joints for instance) to be completely analysed when the variations in direct stress, shear, and bending moment along the lengths of all members have been found

Back 5

rigid frame

Front 6

is a structure in which all members are usually assumed to be connected by frictionless hingers

Back 6

truss

Front 7

the loads on structures consist of dead load, live load and the dynamic or impact effects of the live load

Back 7

loads on structure

Front 8

includes the weight if the structure itself. weight of the flooring, beams, girders and columns

Back 8

dead load

Front 9

is the loading to be carried by the structure. weight of the movable partitions and furniture, etc. snow load and wind load

Back 9

live load

Front 10

is the dynamic effect of the application of the live load, moving or rolling load

Back 10

impact load

Front 11

it was stated that the theory of structures deals with the principles and methods by which the direct stress, shear and bending moment at any section of the member may be found under given conditions of loading

Back 11

methods of analysis

Front 12

is a deformation in a member or flexural member in which parallel planes slide relative to each other so as to remain parallel

Back 12

shear

Front 13

is the property by which a force tends to cause a body to which it is applied to rotate about a point or line, it is equal in magnitude to the product of the force

Back 13

bending moment

Front 14

any one member, part or section, this set free from the whole structure is called a

Front 17

offers resistance in a direction normal to the surface beneath the roller, either toward or away from the supporting surface. It does not resist movement parallel to the supporting surface or to rotation about the roller

Back 17

roller type support

Front 18

prevents movement along a horizontal and vertical direction, but does not resist rotation about the hinge.

Back 18

hinge type support

Front 19

offers resistance in the direction along the link and through the two pins.

link type support

Front 20

resist rotation about support and to movement along the horizontal and vertical directions.
