Cable Structures: Elements of Suspension Bridge, Equilibrium of Light Cable and Suspension Bridge with Three-Hinged Stiffening Girder

by

Cable Cables are slender, flexible members made of a group of high-strength steel wires twisted together mechanically. Steel cables provide the simplest means for supporting loads. Steel cables, which are economically manufactured from high-strength steel wire, have an ultimate tensile strength of approximately 1862 MPa. The wires of cables are formed by drawing the alloyed … Read more

Statically Determinate Arches: Types of arches and Three-hinged arches with support at same and different level

Arches They are very rigid and stable structures which are not considerably affected by movement of their foundations. Arches can be used for large structures made up of materials with negligible tensile strength, such as stones and bricks. Masonry arches of such materials have been used for thousands of years. Types of Arches Arches may … Read more

Influence Line Diagrams for Simple Structures: Moving Loads and I.L.D Beam, Truss and Girder

by

Moving static loads Structure which is used in bridges, gantry girders, crane beams etc. are subjected to loads which change their position often such loads are called moving static loads. Few standard loads are:  Single concentrated load U.D.L greater than the span U.D.L smaller than the span Two concentrated load with specified distance between them … Read more

Strain Energy Method: due to axial stress, bending, torsion, shear

by

Strain energy and Complementary Strain Energy When an elastic member is deformed under the action of an external loading the member is said to have possessed or stored energy which is called strain energy. The strain energy stored by a member so deformed is equal to the amount of work done by the external forces … Read more
