中文摘要 | 本文使用文獻中 77 支角隅梁柱接頭試體所整理成的資料庫,以探討 ACI 318-95 規範在接頭設計條款與相關之補強策略。根據對資料庫中角隅梁柱接頭之設計參數值的調查 與檢核,本文建議 ACI 318-95 規範修訂接頭抗剪有效面積之計算方式,並藉由此一修訂可 以適當地降低 ACI 318-95 規範在角隅梁柱接頭箍筋需求量的 50 %。此外,本文也利用資 料庫來調查角隅梁柱接頭的側向變形能力,以探討接頭之補強策略。由此發現若能藉由增設 如剪力牆等側力抵抗構材,來提供結構的側向強度及韌性,則或許可以更經濟有效地使用接 頭甚佳之變形能力,而避免其破壞。 |
英文摘要 | In this paper the ACI 318-95 design code and the retrofitting strategy related to the corner beam-column joints were investigated by using a data-bank composed of test results of 77 specimens. The collected data of the design parameters reveal that the amount of transverse reinformcement of the ACI 318-95 code requirement can possibly be reduced by 50%, if a modificatin to the effective shear area of joints is adopted. Furthermore, the data-bank was used to investigate the lateral deformation capacity of the corner joint and its application to retrofitting. It is concluded that, if the structure is well equipped with the lateral strength and ductility, the shear failure of joints may not occur due to the excellent deformation abilities of joints. |
