Earthquakes 2Statement of InterestIt is my interest to make a contribution to and participate in the project that focuses on optimization of specific elements for developing earthquake-resistant constructions. The guideline provided below would be influential in assisting the authorities as well as designers of buildings in developing structures that are earthquake sustainable. This technical report focuses on the Nepal region to come up with designs that can preserve the local structures as well as reduce the fatality rate in instances of earthquakes[ CITATION Elg09 \l 1033 ]. Concerning gabble walls, the use of seismic belts has to be secure anchorage to the building providing stable movement that is out-of-plane. When recent structures are considered, gable androof bands have to be put up and in structures that are being built need two gables to be fixed thatare cross-braced[ CITATION Yea151 \l 1033 ].Additionally, vertical reinforcement can be used in masonry walls. These reinforcements improve wall-bending features in strength hence controlling horizontal cracks. This reduces the possibility of walls collapsing. Also, this reinforcement helps in boding roofs to walls by providing controlled shaking and wall support[ CITATION Wau171 \l 1033 ]. WWM reinforcement has to be connected to being installed in an L-configuration outside the L-type wall-to-wall junction with the type T junction also being configured on the outside as depicted in the figures below. The belt is located 300 mm below the level of the plinth and continues to the level of the roof. When rubble walls are used, in situ RC shear connectors with bars that are L-shaped are installed to increase reliability. These hear connectors are to be placed 150 mm from the level of the floor at 600 mm apart. These connectors are placed alternately on the connecting walls[ CITATION Yin181 \l 1033 ].
Earthquakes 3It is possible to use belt encasement round building openings. Typically, masonry walls have piers installed in their openings. These piers are located below and above these openings. In the occurrence of an in-plane motion, the involved walls would rack or rock diagonally beginning from the corners that are open[ CITATION Cor151 \l 1033 ].Other than the use of the above methods, wall stiffening can be applied by using bamboo reinforcement. This system of reinforcement involves strapping of bamboos wit added chicken wire mesh. The used bamboos are mounted horizontally and vertically to the walls for preventionof debris collapse. This reinforcement has been researched and used in Australia to prove its significance in restraining falling debris. Also, there is an inclusion of timber beam rings. The vertically laced bamboos are connected to the timber ring by being nailed. This connection ensures absolute wall support. Such a technique has advantages such as simplicity and reduced design-invasion for the local builders[ CITATION Bre171 \l 1033 ].External cane and rope mesh could also be applied. This reinforcement system involves the use of vertical cane that is being tied with horizontally running ropes to form 450 mm square mesh. The developed mesh is used for wrapping round adobe walls as indicated below. One model of this nature was inspected by using shake table resulting in cracked but restrained debris[ CITATION Zha171 \l 1033 ].In the endeavours of strengthening floors or diaphragms, diaphragm stiffening would be applied by a number of various ways. This includes using steel strap installation. These steel straps are connected to the walls’ exterior to the floors made of timber. Such a connection is achieved by not using nails but bolts. In situations that floor beams are found to be parallel to the wall’s exterior, straps that are V-shaped are connected to the floor before being connected to the floor.
