INCREASING SUSTAINABILITY OF THE HOUSING STOCK BY AVOIDING DAMAGE CAUSED BY THE SOIL-STRUCTURE RESONANCE
Dinu BRATOSIN
In any dynamic system, the coincidence between natural period and excitation period (the resonance) lead to extremely large dynamic amplification. For example a linear system with damping of order 25% the dynamic amplification factor has values between d…

THEORETICAL RESEARCH ON THE MODELING OF CHARACTERISTICS OF COMPOSITE MATERIALS
Constantin D. STǍNESCU, Doina TǍRǍBUŢǍ (ENE),Mariana PǍTRAŞCU (ANTONESCU), Melania TĂMAȘ
the two components of the composite material, i.e., the matrix and the wire, take the requests differently compared with their rigidity. The way the force applied is taken over by composite components and their structural deformities depend on the connection …
