Isolated Footing Design Guidelines Based on ACI 318-14
Isolated or single footings are structural elements which are designed to transmit and distribute loads of single columns to the soil without exceeding its bearing capacity, in addition to prevent excessive settlement, and provide adequate safety against sliding and overturning. ...
Types of Isolated Footings
There are various types of isolated footings such as spread footing, stepped footing, sloped footing etc. They are usually square, rectangular or circular in shape. Each type of footing is selected based on the soil condition and configuration of imposed ...
Components of a Building’s Substructure
The basic components of a building substructure are the foundation and plinth beam. These components safely transfer the load from the superstructure to the ground. Also Read: Superstructure and Substructure of a Building More features of foundation and plinth beam ...
Slope Stability – Causes of Instability, Analysis Methods, and Assumptions
A slope is an inclined boundary surface between air and the body of an earthwork such as highways, cut or fill, railway cut or fill, earth dams, levees and river training work. The slope stability analysis is crucial in engineering ...
Different Elastic Constants and Their Relationships
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 the elastic ...
Bioswale – Design, Applications and Advantages
A Bioswale or biofiltration swale is a narrow strip of a vegetated area that redirects and filters stormwater. A typical bioswale is long, linear and shallow and is used to collect runoff water from non-porous surfaces such as roads, parking ...
What are the Bases of Plastic Analysis of Beams and Portal Frames?
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 ...
Materials for Repair of Concrete Structures – Types and Selection Criteria
There are various types of materials which are used for the repair of concrete structures. For instance, unmodified Portland cement mortar or grout, latex modified Portland cement mortar or concrete, quick setting non-shrink mortar, and polymer concrete. The choice of ...
