Guidelines for Earthquake Resistant Design of Structures
An earthquake is the vibration of the Earth’s surface caused by waves emanating from a disturbance in the Earth’s crust, resulting in the release of energy. It manifests as a sudden and transient motion or series of motions of the ...
Role of Structural Engineers in Designing Earthquake-Resistant Buildings
As someone who has experienced first-hand the devastation that an earthquake can cause, a structural engineer would always be interested in learning about how buildings can be designed to better withstand these natural disasters. When a quake hits, it is ...
How to Repair Structures Affected by Earthquake?
Earthquakes cause distress in structural components of lateral and gravity load-resisting systems (beams, columns, load-bearing walls, and shear walls) as well as horizontal diaphragms (slabs and roofs). Once the structure is damaged, the structure is demolished or repaired depending on ...
How to Retrofit Inclined Columns Damaged Due to Earthquakes?
The required load-carrying capacity of columns damaged due to earthquake can be regained by retrofitting the inclined columns. During earthquakes, the top and bottom parts of a column are most vulnerable to shear forces. If the forces are large, the ...
How to Evaluate Liquefaction Potential of Soils in the Field?
The evaluation of the liquefaction potential of soils in seismic-prone region is essential for site selection, planning, and construction of structures. One can assess liquefaction potential through standard blasting tests, ground response analysis, laboratory tests, and expertise. The use of ...
How to Use Blasting for Deep Compaction of Soil?
Blasting is an economical compaction method that can be applied for various soil types such as granular, silt, clay, loess, etc. Not only is the technique highly effective in loose soil, but also capable of compacting granular soil down to ...
How to Fill Materials in Foundations, Trenches, Plinth, and Flooring? [PDF]
A filling refers to a quantity of earthen material such as murrum, soil, rock, aggregate, shingle, and sand that is placed and compacted in trenches, foundation, and under floors for the purpose of filling in a hole or depression. In this article, ...
