| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 84 === In this study , shaking table tests and time history an
alysis of a model structure are carried out to inve-
stigate the seismic response of R.C. frames with partially
infilled walls . The model structure is a 3-story , 2-
bay , 0.3 scale R.C. frame without fulfilling some seismic
requirements , such as strong column-weak beam , beam-
column joint transverse reinforcement , special transverse
reinforcement in column ends ; in addition , the 1/3-story
height infilled walls make the columns shorter , which in-
creases shear force of the columns . Experimental results
shows that : (1) the model structure is capable of resist
Taft earthquake of EPA equals to 0.46g , (2) plastic
deformation is observed at columns near the top of infilled
walls and the region below beam- column joints , (3) the
stiffness of the structure de- grades dramatically
during large earthquakes due to the presence of cracks .
Analytical investigation reveals that : (1) link elements
in DRAIN-2DX can be use to simulate the crack between
infilled walls and columns , (2)the stiffness of beam-
column joint plays a significant role in structure
stiffness when cracks formed in the joint , (3) the
simple rotational connection element in DRAIN-2DX can be
used to simulate beam-column joint behavior .
