中文摘要 | 本文為無邊界柱樑足尺磚牆試驗與皆析,試體厚度全部為20.5cm,但高、寬比不同共有12個試體,其中6個之高:寬=2:3,試體尺寸為:高240 cm,寬360 cm;另外6個為高:寬=1:1,試體尺寸為:高240 cm,寬240 cm。依施力週次多寡不同可區分為二組,其中一組為單週次正向載重試驗,共8個試體,另一組為多深次政反向載重試驗,共4個試體。 紅磚依CNS試驗法之抗壓強度自9.9至15.9MPa;砂漿5 cm立方塊之抗壓強度自9.2至25.6MPa。12片磚牆試體各施以不同位置與不岣方向之對角軸壓力。由磚礅之抗壓強度,本文可預測無邊界柱梁之純磚牆在對角壓力作用下等值斜撐之P-△曲線。本文發等值斜橕寬度並非定值,而與施力方向角θ成一次線性關係即Ny=-0.2959+0.0144θ,這點與臺大過去將斜橕寬度視為定值(N=1/8.82)不同。 |
英文摘要 | The paper presents the test and analysis of full scale brick walls without boundary elements. There are 12 specimens. 6 of them are 240cm high and 360cm wide. Thickness of all brick walls in 20.5cm. all the specimens are divided into two groups. The first group subjects to monotonic loading: The second group subjects to multiple cycle of repeated loading. The compressive strength of brick unit, according to CNS testing, is from 9.9 to 15.9 MPa. The compressive strength of motar of 45cm cubic is from 9.2 to 25.6 MPa. Diagonal compressive loads are applied to the specimens at different locations with different angles. From basic data of brick pier, this paper predicts P-△ curve of brick wall under diagonal compressive load. Moreover, this paper proposes the equivalent brace width which is not constant but proportioned linearly with orientation angle θ. |
