Reliability of Response Spectrum Curves at Low Frequency Region in Romania), fault directivity, site effects, and so on. Actually, all this factors decrease the reliability of the spectral ordinates at low frequencies and need to be carefully evaluated. Besides they are important in assessing the seismic performance of base-isolated structures at high risk cond厨房里面 发表于 2025-3-27 12:38:18
A Note on Empirical Site Responses in Bucharest, Romaniaquakes by the new K2 network corroborate that the high frequency peak ground accelerations (PGA) may differ up to 2–3 times in downtown Bucharest. However, lowpass filtering with a corner frequency of 1Hz reduces these differences from several 100% to about ±15%, thus confirming the almost constant头盔 发表于 2025-3-27 14:22:29
Dynamic Behaviour of High Damping Rubber Bearings for Building Seismic Isolationever, this concept may lead to a very high interstory drift, causing P-Δ effects and damage to non-structural elements. Thus, the costs for retrofitting or strengthening after a strong earthquake can be very high. An alternative approach consists in isolating the structure base from the ground by us谦卑 发表于 2025-3-27 19:40:28
