In the aftermath of earthquakes and other natural disasters, there is a great deal of destruction and chaos. Collapsing buildings and homes cause a lot of casualties. Making your home or building earthquake-proof is important, so make sure you know how.
Building materials' resilience and strength are not the only factors that determine how well they can withstand an earthquake, but also how they are integrated into the structure. If a long, straight stone wall relies solely on friction and geometry to hold stones in place, it is almost certain that it will collapse in an earthquake. As a result of the wall's mass or inertia, its motion lags behind that of the earth during a quake. It can also cause the weight of the wall to shift so far out of the stable load line that it tilts over, not only dislodging stones from their resting position but also shifting the wall's weight out of the stable load line.
Following are some earthquake-resistant construction techniques you can use to build your home.
Horizontal bands are used here :
On the building's plinth level
At the lintel levels like doors and windows
At the roof levels
Types Of Horizontal Bands :
It is possible to implement all of the methods mentioned thus far in safe construction practices for earthquakes without incurring additional costs, regardless of the specific construction materials used. Wood frame, adobe, rammed earth, and seismically active masonry construction may also incorporate low-cost, material-specific methods. By using the right brackets, hold-downs, and fasteners, wood frame construction can be seismically strengthened. Screws indeed appear to have greater holding power, but they tend to be more brittle and break under load than nails. A shear wall, brackets, and gussets are commonly used to reinforce beams, joints, corners, sill plates, and roof trusses in this type of construction.
The massive weight and brittle composition of adobe and rammed earth walls make them vulnerable to seismic failure, especially at corners and long walls, causing large pieces of the structure to fall. To reduce cracking and keep the pieces in place, you can incorporate reinforcement fibres, bars, rods, or mesh into the walls. The material can be reinforced internally with straw, vines, or synthetic yarns. Ropes, plants, vines, twines, or bamboo can be used to connect wooden bars and rods at intervals to foundations, wall caps, and each other. It is especially effective at corners to use mesh reinforcement, such as screens, chicken wire, and so on, to connect walls and distribute horizontal forces.
