SuperAdobe – History, Construction, and Advantages
A super adobe structure is a man-made building made of sandbags (small or long) with the native material available in abundance and stacking or putting them in a layer that is reinforced with barbed wires. Superadobe is extensively used in ...
Twisting of Buildings During Earthquakes- Causes, and Effects
Twisting of buildings is one of the factors that cause severe damages during earthquakes. This commonly occurs in buildings due to stiffness irregularities in plan and elevation of buildings, and mass irregularity in plan and elevations of buildings. So, when ...

There are several weaknesses that may cause the failure of unreinforced masonry structure during earthquakes. These weaknesses are design and construction errors which should be considered and addressed during the design and construction of such structure. The main weaknesses in ...
What are the Four Virtues of Earthquake Resistant Buildings?
There are four virtues that any earthquake resistant buildings should have to a certain extent in order to withstand designated seismic forces. The virtues of earthquake resistant buildings are structural configurations, lateral strength of the building, adequate stiffness, and ductility. ...
I.S Codes on Earthquake Resistant Building Design
The list of Indian standard codes for earthquake design of structures include IS 1893–2002, IS 4928–1993, IS 13827–1992, IS: 13920–1997, IS: 13935–1993. These codes take several parameters into considerations for instance local seismology, accepted level of seismic risk, building typologies, ...
Difference Between Magnitude and Intensity of Earthquake
Magnitude and intensity measure various characteristics of earthquake. The former measures the energy released at the source of the earthquake. However, the latter measures the strength of shaking generated by the earthquake at a certain location. The magnitude of earthquake is ...
