| 摘要(中) |
本研究在探討真實倍力橋一路一桁兩框、二路一桁兩框、三路一桁兩框、二路二桁兩框與三路二桁兩框的形式在車輛荷載下，受垂直推力之極限承載力與受水平推力之最大基底剪力與其相對應位移。先探討二階修正塑性鉸法與二階簡單塑性鉸法的理論基礎，然後說明以二階修正塑性鉸法所撰寫的2MP程式與SAP2000降服曲面判斷準則之間的差異。接著分析一層與三層之門型剛架、以矩型鋼與槽型鋼所模擬的倍力橋實驗之相關例題驗證，再以使用SAP2000對三維空間結構的側推分析功能，分析前述五種形式的倍力橋之彈塑性行為，探討真實尺寸的倍力橋之破壞機構塑性鉸產生過程與位置，提供有關單位在使用倍力橋之參考。 |

The object of this
research is to investigate the ultimate-load and base shear of Bailey
bridge including the Single-Single two Panels, Double-Single two Panels,
and Triple-Single two Panels, and Double-Double two Panels, and
Triple-Double two Panels under vehicles. First, this thesis investigates
the basic theory of the simple plastic hinge method and the modified
plastic hinge method. Then, the differences between the program 2MP
written according to the modified plastic hinge method and the program
SAP2000 written according to the simple plastic hinge method were
studied. Next, steel frames with one-story and three-story were used to
verify the computer programs. Then, some Bailey bridge experiment
results were used to verify the computer programs too. The experimental
models were made by steel whose members had channel and solid
rectangular sections. Finally, the functions of pushover analysis in
SAP2000 for three dimensional structures were used. The elastic-plastic
behavior of Bailey bridge was studied. This study investigated positions
of plastic hinges in the course of pushover analysis of Bailey bridge.
The results of study are suggested to the related departments for
reference. |
