Earthquake resistant design of buildings
(57) Abstract:Earthquake resistant design of buildings differs from known more flexible relationship with the Foundation. Such connections are practically resolve the transfer of perturbation with any amplitude on the block floors, and thus eliminate any force on accommodations. Such properties of the building acquires due to the fact that the relationship between the unit floors and foundations over the counter via the aquatic environment, where they are connected through capacity with positive buoyancy. 2 Il. The invention relates to devices of the building for use in areas with increased risk of earthquakes and can be used for construction jobs multistory also for all parts of the country, i.e., an earthquake occurs and in areas that were not previously exposed to natural disasters.Known technical solution, when the building is provided with a hinge supported by piles 
The drawback of this design of the building should be considered: a large enough radial force, i.e. the friction between the mating surfaces and determines the mass and the coefficient of friction, which will lead to the transmission of vibrations almost without weakening samor of gravity of the system is located above the support structures, that creates unfavorable conditions for damping.Known technical solution for the seismic design of the building containing the through shaft placed inside the hollow stand, which is anchored in the Foundation and mates with the block floors in the radial direction through the damper, and block floors located at the top and bottom and connected by rods between the plates 
Disadvantages described technical solutions should be considered:
the connection plates with a rack that virtually eliminates non-rigid connection, as the cable connections must be rigid compared to the weight of the floors of the building,
the transfer of mechanical stress from the hollow stand on the block floors through dimensional communication connection with the upper plate,
the radial transmission of impacts from the rack on the block floors through the absorbers, as the scheme of loading corresponds to the console with the location of the mass on the end of the console, vertical positioning of the console, when there would be increases stress in the rack with the growth of the oscillation amplitude, which will be aggravated by the deviation of the mass of the block floors.The purpose of the proposal is to eliminate these disadvantages, Amy block floors which ensures the elimination of increasing stress in the block floors fluctuations in hours for both radial and horizontal.This objective is achieved in that the building is equipped with a bowl and a hollow container, which are connected respectively with stand and block floors, and capacity combined with the bowl and the space between them filled with water.In Fig. 1 presents the seismic design of the building as a structural schematic of Fig.2 section a And in Fig.1.The building contains a block of floors 1, a shaft 2 which is placed in hour 3, which is made hollow and is secured to the Foundation 4. Hour 3 in its upper part has a Cup 5, which has a capacity of 6. The tank 6 is connected with the upper plate 7, which is connected by rods 8 with the bottom plate 9. Between the Cup 5 and the container 6, the cavity is filled with water 10. The bowl 5 and the container 6 provided with ribs 11, 12, which are interfaced with a gap corresponding to the maximum amplitude of vibration of the soil in the radial direction, the same gap and between the Cup 5 and the container 6. At the same time the ribs 11, 12 are limiters of the relative movement. Between the bar 3 and the shaft 2 is installed dampers 13. The flexible connection of the supply, SS="ptx2">Operates the device as follows.The installation is on blocks under the bottom plate 9, when filling the cavity between the Cup 5 and tank 6 water 10 will be floating block of floors 1 and stops will be exempt from loading. When the earthquake will occur moving soil, Foundation 4 and 3 hours. These vibrations will not be transmitted to the block of floors 1, as the water 10 relative to the aforementioned movements virtually no hydraulic resistance, and the movement is very small, so the block floors will remain stationary at any vibrations of the rack 3. To take into account connection for water supply, power has no meaning compared to the mass of a block of 3 floors. In the worst case will break them, and if their design (which are known) are the angular and linear compensators, and breakage will not occur, and move fully perceived by the expansion joints.You need to make the following comments:
1. Capacity 6 shows made in the form of single stage cylinder, it can be done and two with a sunset in the cylindrical part of the hollow rack. This is equivalent technical solutions, but, as will be shown below, this is not the best way to run the building.the heat. The communication between the floors need to be flexible.3. The shock absorbers in fact serve only to compensate for the unbalance mass block floors, if the center of mass coincides with the axis of the rack 3, the damper 3 is not needed. In the building to install three 3 hours and the level of the water 10 to align the masses, then the damper 13 can be eliminated. This is equivalent technical solution.4. Thrust 8 can be located near the mine, as well as to serve as a continuation of the connection of the tank 5 through the upper plate 7 (may be a hole in the top plate 7) with a bottom plate 9, then the connection is advantageously made in the form of cables. This implementation is more favorable from the point of view of the loading unit of floors 1. The internal cavity of the container 6 can be used as a warehouse, auxiliary premises, of course without overloading
5. If the capacity of 6 to perform closed-loop, water cavity above it can be used as a pool. The reality of such execution earthquake resistant building construction shown in approximate calculation.6. When performing fixing capacity on the cables necessary pulleys to change the direction of the effort. In this case, the need for rods between the plates 7, 9 upadate pressure vessel 8. Restrict movements can be used ribs 11, 12 and a flexible connection with the communications.Thus, the proposal allows to achieve all the set goals and to ensure reliable seismic design simple means and to increase porozumienie of the building while providing a reliable evacuation in the event of a fire. Earthquake resistant building design, including mine, formed by the block floors, which has upper and lower plates, a hollow rack placed in the mine, mounted in the base and connected to the block floors, characterized in that the building is equipped with a bowl and placed it by the hollow container with the formation of a cavity between them, and a Cup mounted on the rack, capacity connected to the block floors, and the space between the bowl and the tank filled with water.
