Equilibrium equations is the greatest need of construction in terms of earthquake loadings .
The loadings , external and static there will always be
We can not stop or earthquake loadings and air or static loads .
But we can change direction , and lead them where we want them ,
in order to balance it charges , which balance can only be achieved with voltages (equal or bigger charges ) which would preclude these loadings .
These opposing tendencies balance to the side of the earthquake loads , apply the vertical load-bearing elements .
The vertical elements have two sections .
The horizontal section and the vertical .
The horizontal cross section of vertical structural elements , is much weaker than that is the vertical cross section of vertical structural elements .
So it is logical that if we want a strong cross-section which will oppose the lateral earthquake loads to balance them , this is the vertical cross section of the bearing elements .
In this vertical section should lead the earthquake lateral loads to balance .
With the current design , these trends apply balance of small sections of vertical and horizontal structural elements , which sections are unable to pit balance trends in lateral acceleration loads a large earthquake.
The result is the failure of these sections .
The roof anchorage ground ( all bearing vertical elements ) deflects lateral earthquake loads and directs the vertical profiles of vertical structural elements , which are more powerful than the horizontal , and have the ability to pit trends and more equal balance of these lateral earthquake loads .
The result is to achieve the desired balance equation .
This is NEW in seismic design , and is the solution to the devastating effects brought about by earthquakes in the construction works .
This is a trend on extra balance , because it eliminates the tendencies balance of small sections, but only adds more responsive .
Failure to restrain all bearing vertical elements with the ground , it creates a chain reaction , putting and static loads of construction to cooperate with loads of earthquake , increasing the destructive work.
This is because the non- clamping of the bearing soil roof of each component is changed from a few degrees on the vertical axis , the existing ratio oscillation of the building.
Because bearing vertical elements is combined with horizontal node , the movement of hand, do not affect the resulting columns to try to go over the post - below .
This movement of the anode beam is in contrast to the static loads of the building which are always vertical direction.
This contrast of loads has resulted in creating moments that are mutated in shear , and is an additional strain on small sections, which complements the earthquake lateral loads , which result in cutting these small sections .
This additional stress loads of the building , stopping when she stops and vertical deformation of the load bearing vertical elements . ( Oscillation )
This can only be achieved by clamping or pretension roof soil .
And this is another NEW in seismic design offers patent .
And many more ....
