Abstract

For the numerical simulation of the earthquake behavior of masonry buildings experience-and performance-based vulnerability functions for typical masonry constructions are developed. Therefore, the magnitude ML 5.7 Albstadt earthquake from September 3rd, 1978 (intensity VII–VIII) is reconstructed for the building stock existing at that time. As a whole, 1300 damage cases are reevaluated. As an outcome of archive studies, original construction plans of the buildings are elaborated. For more about 40 objects the floor and vertical section elevation plans are digitized enabling a systematic check of the correlation between “simple masonry rules” and the observed and numerical predicted earthquake damage. The vulnerability of the building types is determined parallel in three different ways:
(1) Empirical-statistically, on the basis of observed damage and assignment of the most likely and still probable vulnerability classes (acc. to EMS-98 procedure).
(2) Analytically, on the basis of displacement-based (Pushover Analysis) approaches and checking the outcome of different software tools.
(3) Experience-based, using a hybrid approach combining the evaluation by constructional parameters and torsion susceptibility within capacity curves calculated by EDAC software tools.
The effect of local site conditions is considered assigning instrumentally derived spectrum types acc. to DIN 4149 (2005).
