“…Period-related adjustments will need to be made to compensate for ground conditions different from rock, and these may also recognize the non-linear effects. Such effects, including the lesser amplification of strong motions under strong shaking, the deamplification of short-period motions on thick soils, and the change in spectral shape according to soil softness were already included in a non-site-specific way in the response spectrum approach of KTP-N.2-89 [29]. However, KTP-N.2-89 considered only amplification of the computed hazard relative to Soil Category I (rock or firm soil), and gave no credit for sites on rock rather than firm soil.…”

SUMMARYAlbania is a Balkan country with high rate of seismicity, and earthquake risk reduction has been an important, on-going socioeconomic concern. We adapt the experience and methods used for Canadian seismic hazard maps to present, for the first time, probabilistic spectral hazard maps for Albania. A revised catalogue of Albanian earthquakes, from 58 A.D. to 2000, with magnitude Ms>4.5 in the region between 39/N and 43/N and 18.5/E and 21.5/E was used in this study. Ten seismic source zones are used to define the seismicity. We have used the Ambraseys et al. (1996) strong ground motion relations for rock to produce 5% damped spectral acceleration values at 0.2, 0.5, 1.0 and 2.0 seconds (as well as peak ground acceleration) for a return period of 0.0021 per annum (equivalent to a 10% chance of non-exceedence in 50 years). The four spectral parameters maps will allow the construction of site-specific Uniform Hazard Spectra for all of Albania, and are suggested as the basis of the next version of the KTP-N.2-89 Technical Aseismic Regulations to improve earthquake-resistant design code in Albania.

“…The history of methods applied for the computation of earthquake response spectra is presented in detail in Trifunac (2006) and some methods of estimating response spectra are reviewed in Dumbar and Charlwood (1991). The influence of local soil conditions on the response spectra is discussed in many papers (e.g., Myslimaj and Matsushima 2000, Chopra and Choudhury 2011, Smerzini et al 2014, Borcherdt 1994, Malhotra 2003). Other earthquake parameters (e.g., epicentral distance and focal depth) can also significantly affect the response spectra, in addition to the site conditions (Pitilakis et al 2013, Tehranizadeh and Hamedi 2002).…”

Response Spectra of Ground Motions and Building Foundation Vibrations Excited by Rockbursts in the LGC Region

Surface vibrations induced by mining rockbursts resulting from underground exploitation in the mines in western Poland were analyzed and classified into three different categories. Comparison of the accelerograms simultaneously recorded on the ground and on the foundations of typical buildings, as well as the response spectra determined on the basis of these records, leads to the conclusion that ground vibration characteristics have a significant influence on the nature of vibration transmission from the ground to the building foundation. Analysis of the response spectra, separately determined from both ground vibrations and building foundation vibrations, indicates that the standard response spectrum based on building foundation vibrations is more useful in the design of new buildings in areas of mining tremors than the spectrum based on ground vibrations. Moreover, the usefulness of the models of soil-structure interaction based on seismic data in California was investigated with respect to mine-induced rockbursts in Poland.
