It is the goal of every civil engineer and structure designer to design and create buildings that are earthquake resistant. The buildings designed by a structure engineer should suffer minimum damage during earthquakes. Following are the 4 virtues of earthquake resistant building design discussed in detail.
Good Lateral Strength
Buildings should possess good strength in lateral directions to bear the earthquake stresses.
Good Lateral Stiffness
For a building, it is vital to have good lateral stiffness. Good lateral stiffness ensures that deflections are not excessive and damage will be the minimam.
Proper Ductile Detailing
If a building has properly detailed for ductility, then only non-load bearing elements will be prone to collapse. Also, important elements of buildings will suffer less damage. Good ductility will allow deformation between base of the building and the roof of it.
Good Structural Configuration
This could be achieved by proper positioning of beams and columns. Moreover, the size, shape, and reinforcement of all the elements should be chosen with highly analytical thinking.
These are the 4 virtues that drive the design to be earthquake-resistant.
