Erdbebensicherheit mehrgeschossiger Holz- und Mauerwerksbauten – Auswirkungen nationaler Regeln auf die Baupraxis/Earthquake resistance of multi-story timber and masonry buildings – effects of national rules on construction practice

This paper presents a study with comparisons between different national standards of European countries regarding the seismic hazard of low-rise building structures. For this purpose, points were selected, in which the borders of three European countries meet, the so-called Tripoints. Recent studies carried out by seismologists show that the models used to generate the response spectra in these European countries should lead to consistent results, in these analyzed Tripoints. In the current European national standards, howe-ver, considerable differences can be found in the maximum spectral accelerations as well as in the reference periods of the spectra for all the selected Tripoints. Using a four-story reference building, the effects of these differences will be analyzed and discussed. Two different construction typologies were con-sidered: unreinforced masonry shear walls and wall elements with cross-laminated timber (CLT). The results of this study show that masonry structures are more sensitive to the increa-se of spectral accelerations than timber structures.
