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…

CONSIDERATIONS ON CONTACTLESS ELECTROMAGNETIC TECHNIQUES FOR MEASURING SOIL CONDUCTIVITY
Tudor BURLAN-ROTAR, Constantin STANESCU, Melania TAMAS
Conventional determination of resistivity by galvanic method requires a relatively large amount of labor to apply them in practice and is therefore expensive. It is the lateral or vertical variations of resistivity which form the basis of any interpretation. …
