| Research Abstract |
Four reinforced concrete columns with wing walls were tested to evaluate the effects of spandrel walls on flexural capacity and maximum strength of those members. The hysteretic behavior was compared in the static cyclic loading test between specimens with spandrel walls and with rigid beam at the bottom of the wing walls, which have identical critical section and shear span length. The maximum strength of spandrel specimen shows smaller value rather than rigid-beam specimen for thin wall-type case, while both specimens show identical strength for thick wall-type case.
