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 load of ...

What are the Effects of Earthquake on Structures?
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. That is ...
Stress-strain Curve for Steel Bars
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. The stresses ...
Construction of Wall Footings – Materials, and Dimensions
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 is not ...
Raft Foundation — Design Requirements and Applicability
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 foundation may ...
Difference Between Braced Frame and Moment Resisting frame
Both, braced frame and moment resisting frame are used in the construction of structures which are subjected to lateral loads such as wind and seismic forces. This is particularly obvious for very tall structures where the lateral forces are the ...
How Stresses are Transferred from R.C. Columns to Footings?
A proper understanding of the transfer of stresses(generated due to applied loads) from columns to the footings or piles is crucial for the design of sound footings. Factored forces and moments at the base of columns are transferred to the ...
What is Tributary Area in Columns?
Tributary area is the area surrounding the column that is bounded by a panel centerline. In order to calculate the forces and static loads transferred from floor slabs to the columns tributary area method is used. Commonly, designers use tributary ...
