| Summary: | 碩士 === 朝陽科技大學 === 營建工程系碩士班 === 98 === At present, most of the domestic simulations on the closed basement wall in a high-rise building will increase the loading capacity of columns without simulating the closed basement wall. However, for the part of underground structures, the existence of successively closed walls, if any, will actually affect the internal force of external beams and columns. If we left the strength or effect of closed walls out of consideration in the stage of structure analysis, there would be somewhat actual behaviors which are inconsistent with the structure, such as over design or inadequate design.
This study analyzed the influence of closed basemen walls onto the column axial force. In the first stage, this study found the change of column axial force in the basement and the effect of closed basement walls onto the column axial force through the building affected by the closed wall in different locations while the wall thickness is changed. In the second stage, this study made an analysis of the zero self-weight wall to find the impact of self-weight of the wall on the column axial force. In addition, this article also made a comparison with the model having the self-weight of the wall to further understand if it was the key factor influencing the column axial force.
The result of this study showed that the closed basement wall is obviously helpful for the load of the column axial force and the self-weight of the wall also has a certain influence on the column axial force. It is not true that the thicker the wall is the bigger the column axial force is. Instead, the column axial force will increase because of self-weight of the wall if the wall are too thick.
