| الوصف: | Themajority of industrial buildings located in our country consist of single-storyprecast systems with pinned beam-to-column connections. Observations made afterearthquakes showed that due to high lateral displacement demands occurred underthe effects of earthquake loads; significant damage was accumulated throughoutthe beam-to-column connections and whole structure. Strengthening such buildingsystems against earthquake loads is not only crucial for high-cost devices andmachinery but also very important in terms of human life as a priority. In this study, the effects of reinforcedconcrete (RC) jacketing technique on the global earthquake performance ofprecast structures was examined numerically. In the first part of the study,experimental results of bare and RC jacketed columns, which exist in the recentliterature, were used as a benchmark for the development of numerical models.The force-displacement relations obtained from quasi-static experiments werecompared with the numerical results. The numerical models are successful toestimate the experimental results within the range of distinct displacementlevels. Validated numerical models were used for nonlinear dynamic analysis ofan existing 3D precast system. Numerical results showed that the application ofRC jacketing technique is effective to decrease the average maximum and minimumdrift values by the ratios of 54-72%. Determinations of strain levels for theselected columns of the system showed that; the RC jacketing retrofitting techniqueis effective to increase the sectional performance by shifting the straindemands from safety limit (GV) to minimum damage limit (MN). ; Ülkemizdeki sanayi yapıların çoğunluğunu, kolon‑kirişbirleşim bölgelerinde moment aktarımı olmayan tek katlı prefabrike sistemlerioluşturmaktadır. Yaşanmış depremler sonrasında yapılan gözlemler; prefabrikeyapıların deprem etkisi altında yüksek yatay yerdeğiştirmeleri nedeniyle kolon‑kirişbirleşim bölgelerinde ve yapı genelinde önemli hasarların oluştuğunugöstermiştir. Bu tip yapı sistemlerinin ... |
