| Summary: | 碩士 === 國立中興大學 === 土木工程學系所 === 94 === To simplify calculations, typical structural engineers often ignore the structural properties with T-section beam effect, and that is often considered the conservative method.
However, if these structural properties were ignored, under the excitation of earthquakes and other disasters, it would be difficult to dominate the actual condition of structure. This thesis is to analyze and compare the dynamic properties of building with T-section beam effect with popular structural design (without T-section beam effect).
Studies found that structures with T-section beam have much shorter structural period than ordinary structures (without T-section beam).Moreover, the distribution of the structural internal force would be very different. Without considering the stiffness of beam and floor slab assembly, the design steel sections of beams and columns would be impractical demand. The actual hinges position and sequence would mismatch with the initial design. Due to its short period characteristic, bring seism-excitation would become stronger. Without taking the T-section beam effect into structural design, we often underestimate the structural design seism-excitation. For the sake of safe structural design, T-section beam effect is an essential concept.
