Competitive Comparison of Load Combination Models

Popis výsledku v původním jazyce

Civil engineering structures are, as a rule, exposed to time-variant actions such as imposed or climatic loads. Selection of an appropriate model for load combinations may be one of key issues of reliability studies. Models for load combinations are often based on the rule proposed by Turkstra (1970) that is considered to be particularly useful for probabilistic calibrations. Despite numerous applications, accuracy of Turkstra's rule seems to be insufficiently analysed yet. The submitted study attemptsto re-investigate and improve the findings considering the combination of two independent variable actions, different load ratios and various types of processes. Reliability of a generic structural member is analysed focusing on serviceability as well asultimate limit states. Results obtained by Turkstra's rule are critically compared with those based on Ferry Borges-Castanheta processes and rectangular wave renewal processes with intermittencies.
