本論文為研究鋼骨柱與RC柱軸力傳遞的行為，進行了有限元素分析以及單向軸壓試驗探討，實驗共完成5組共28個混凝土墩柱試體，包含配置縱向及橫向鋼筋混凝土墩柱以及純混凝土墩柱，部分試體配置有承壓鋼筋，進行軸向載重試驗，研究鋼骨柱與RC柱軸力傳遞的行為。研究顯示：
(1)橫向鋼筋可以提升混凝土墩柱的承壓強度及延展性，承壓強度最多可以提升54 %，軸向延展性可以提升825 %；(2)相對於外箍筋，配置於承壓板下方的橫向鋼筋，可以發揮出較大之效益，最多可提高18 %的承壓強度以及26 %的軸向延展性；(3) RC墩柱承壓機制有兩種破壞模式，當√R大於2.0時，承壓面的應力集中嚴重，試體軸向延展性較佳;當√R小於2.0，試體軸向延展性較差，且試體破壞時，試體側向開裂嚴重；(4)墩柱試體的高寬比對承壓強度的影響不大，但對軸向延展性影響劇烈，當試體高寬比從1.0提升至1.7，承壓強度僅下降2.6%，但軸向延展性下降21%；(5)距離承壓面越遠的橫向鋼筋，對承壓強度的貢獻越小。(6)本研究建議之承壓強度評估公式，可以準確的預估斷面尺寸為30×30（cm2），√R小於3.0的RC墩柱承壓強度;(7)本研究設計的承壓鋼筋可以有效的傳遞承壓力給下部混凝土，約可提供一半的鋼筋降服應力。

Experimental and analytical studies were conducted to investigate the axial force transfer of steel column to reinforcement concrete pedestal. This research conducted load tests of 5 series with a total of 28 concrete pedestal specimens. The parameters studies included amount of transverse reinforcement, pattern of the transverse reinforcement, size of the bearing plate and the use of bearing steel bars. Based on the test results obtained, the following conclusions can be drawn:
(1) Transverse reinforcement can increase the bearing strength up to 54 % and ductility up to 825 % of the RC column ;(2) Compared with the external stirrups, the horizontal reinforcement placed under the bearing plate can exert a greater effect, increase up to 18% of the bearing strength and increase up to 26% of the axial ductility ;(3) The aspect ratio of the RC pedestal has little effect on the compressive strength, but it has a great effect on the axial ductility. When the aspect ratio of the specimen is increased from 1.0 to 1.7,the bearing strength decreases by only 2.6%, but the axial ductility drop of 21% ;(4) RC pedestal pressure There are two failure modes in the bearing mechanism of RC pedestal. When √R is larger than 2.0, the stress concentration of the bearing surface is serious and have better axial ductility. When the √R is less than 2.0, the axial ductility of the specimen is poor and the specimen have severely lateral cracking ; (5) The greater the lateral reinforcement from the face, the smaller the contribution to the bearing strength ;(6) The design formula proposed in this study can accurately estimate the bearing strength of RC column with cross section of 30×30 (cm2) and √R less than 3.0 ;(7) The bearing steel bars designed in this study can effectively transmit the pressure to the lower concrete, it can provide half of the yielding strength of rebar.
