The ideal solution to protect the buildings from earthquakes is to control and limit the transfer of the seismic energy to a construction by the maximum dissipation of the seismic energy transferred to the building, which is achieved by the use of mechanical devices with which the seismic behavior of buildings is controlled. The protection of the structures exposed to the risk of earthquake is based on the three fundamental operational modes: insulation, connection, dissipation of energy. The centrically braced metallic frames provide resilience, rigidity and ductility, being thus ideal for the bracing of the seismic systems. Seismic insulation systems are designed to reduce the impact of earthquakes on buildings by means of special devices. Seismic protection of an overground parking over the Dambovita river by using the basic containment method. The anti-seismic protection system. [ABSTRACT FROM AUTHOR]

In the event of an earthquake, the energy radiates outward as seismic waves. The inner waves (longitudinal and transversal) move from the hypocenter to the outside, and the superficial waves move to the surface of the earth, those resulting from the inner waves that reach the surface of the soil.The P and S type of internal longitudinal and transversal seismic waves represent disruptive forces for any system. We propose to evaluate the own pulsation in case of the free vibrations of an overground parking. it is necessary that the wave pulsation to be different from the own pulsation of the system to be researched in order to avoid the phenomenon of resonance that is leading to the destruction of the system. We will consider the System Model with a degree of freedom for which we will determine its own pulsation and frequency. [ABSTRACT FROM AUTHOR]

The cogeneration installations have experienced a particular development due to the energetic crises and, as a result of the Kyoto Protocol, regarding the reduction of the emissions of greenhouse gas. Cogeneration advantages: energy efficiency, economic and ecological advantages. [ABSTRACT FROM AUTHOR]

This work deals with the need and possibility of building car parks in Bucharest above Dâmboviţa river. They included analyses referring to the evolution of the number of existing vehicles in Bucharest, an analysis of the number of vehicles in Bucharest, as compared to other European capitals, and also certain elements leading to the possibility and profitability of building a car park above Dâmboviţa River.

The paper deals with the types of automated parking facilities in operation, taking into account the advantages and problems induced by them. There are presented underground parking, one-and two-platform elevators and their mechanisms, as well as robotic parking along with the existing mechatronic system. [ABSTRACT FROM AUTHOR]
