Influence line represents the variation of either the reaction, shear, moment, or deflection at a specific point in a member, as a concentrated force moves over the member. Influence lines are important for the design of a structure ...
Concrete frame construction is a construction method which comprises a network of columns and beams to transfer the loads coming onto the structure to the foundation successfully. Wholistically, it forms a structural skeleton for the building which is ...
When an elastic body is subjected to stress, a proportionate amount of strain is produced. The ratio of the applied stresses to the strains generated will always be constant and is known as elastic constant. Elastic constant represents ...
Plastic analysis is the method through which the actual failure load of a structure is calculated. This failure load can be significantly greater than the elastic load capacity.In plastic analysis and design of a structure, the ultimate ...
Earthquake is the most dangerous natural phenomenon that generates sizable destruction in structures. It is reported that two sources of mistakes which would seriously endanger structures are ignoring the ways an earthquake affects buildings and shoddy construction practices. ...
The stress-strain curve describes the behavior of steel bars under loads. It is created by testing steel specimens. A steel specimen is gradually pulled through a testing machine until it breaks, and stress and corresponding strains are recorded. ...
Wall footings are pad or spread and strip footings which are used to support structural or nonstructural walls to transmit and distribute the loads to the soil in such a manner that the load-bearing capacity of the soil ...
A raft or mat foundation is a sizable concrete slab or slab-and-beam system which supports all the loads of superstructure through walls or columns in two or more rows and rests on soil layer or rock. A raft ...
