An industrial product has the same specifications. The constructions, however, differ from each other and each have different needs and different concerns.
Also..The soils are inhomogeneous due to their natural composition and have different strengths.
Also .. the mechanism with the tendon and the ground may lose their dynamics after a strong earthquake or over time.
There are also existing structures that need seismic reinforcement
There are too many unbalanced factors that can cause disaster in most modern seismic structures. Basically, the factors that determine the seismic behavior of structures are numerous, and in part probable. (The direction of the earthquake is unknown, the exact content of the seismic excitation frequencies is unknown, its duration is unknown.) Even the maximum possible accelerations given by seismologists, and determine the seismic design factor, have a probability of exceeding more than 10%. These unbalanced factors when combined all together cause large deformations in the structure which create from inelastic leakage failures to beyond their breaking point and we have the collapse of structures. According to modern regulations, the seismic design of buildings is based on the requirements of adequate design and plasticity. The inevitable inelastic behavior under strong seismic excitation is directed at selected elements and failure mechanisms. In particular, the lack of good design of the nodes and the clearly limited plasticity of the elements lead to fragile forms of failure. In short they inevitably manage failure which they cannot control because they cannot control deformation.
1) If the anchoring mechanism is placed in a continuous brickwork construction (without columns) it keeps the consistency of the bricks. 2) If the anchoring mechanism is placed on all the sides of the reinforced concrete walls by connecting with partial pre-tension.. using tendons without relevance, joining their upper end and the ground together ... then we stop ....
a) the overturning of the wall.
b) the bending of its trunk.
c) the critical area of ​​shear failure. d) The torques at the nodes.
e) returns deflects seismic forces into the ground Basically we stop the deformation of the building and in this way we stop the failure. The ground mechanism successfully receives up and down loads on both soft and rocky soils
If the soil is liquefied then go drilling deeper.
