摘要: 
一般結構工程師為了簡化計算,多半忽略樑版所構成之T型樑效應的結構特性,且以簡化計算視為保守的行為。但實際上忽略此結構特性,當結構物遭受地震或其他災害來臨時,將無法確實掌控結構物於各種外力作用下的實際行為。故本論文藉由分析T型樑的動態特性與一般結構設計(未含T型樑)做比較,討論其中差異。
研究發現含T型樑之結構,其整體結構週期會相較於一般結構(未含T型樑)縮短許多,且結構內力的分布形式,亦會大不相同,在不考慮樑版組合(T型樑)所提供之勁度之下,將會造成樑柱斷面配筋設計不符合實際需求,相對於塑角發生位置與順序亦會與設計時不相符合,且因週期縮短,將會引致較大的地震力,與原先設計之一般結構比較,其會低估結構之設計地震力。故為求安全之結構設計,考慮T型樑效應,有其必要性。

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.
