| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程系 === 100 === Reinforced concrete is a complex composite material. we use conservative safety factor to ensure its structural strength in Taiwan specifications so far. If we can simulate the actual nonlinear behavior of reinforced concrete material, we will have a further understanding.
This research used the package SAP2000 built-in nonlinear link and plane stress element to simulate the nonlinear behavior of reinforced concrete members. It also include concrete, steel bars, cracks, and bond slips. As a result of the SAP2000 cannot deal with the negative stiffness caused by concrete cracking, so we developed a set of equivalent analysis processes to get through this negative slope segment. The research shows examples to explore the simulation accuracy and to display the results in graphical. Compare with the results of the steel stress from linear theory to prove that this method has very good accuracy.
