摘要

本文依據土木401-93規範[1]建議，參考規範附篇A壓拉桿模式之設計理念，提出一套梁柱接頭剪力強度之計算流程，並將本文模式、土木401-93規範第15.6節計算結果與實驗數據比較，實驗數據來自國內外學者。結果顯示，目前土木401-93規範第15.6節對梁柱接頭剪力強度之計算值變異較大且有高估現象，而本文根據附篇A壓拉桿模式所提出之計算模式，評估結果與實驗值較為接近。

Present paper developed a shear strength evaluation model for reinforced concrete beam-column joints. Using the concept of Appendix A in Civil 401-93 code, present paper developed a shear strength model based on the strut-and-tie model. The present model have been used to predict the shear strength of beam-column joints. The results of present model are compared with the results of the section 15.8 in Civil 401-93 code and the experimental data from the published literatures. It is seen that the present model is quite well.
