（同濟大學(xué)，上海 200092）[摘要]通過比較分析中美規(guī)范關(guān)于錨栓在混凝土中抗拉設(shè)計的方法，介紹了錨栓在混凝土中的各種破壞形態(tài)和對應(yīng)的承載力計算方法，為了充分利用錨栓的抗拉強度同時又避免混凝土的崩裂破壞而導(dǎo)致錨栓被拉出，本文給出了通過利用基礎(chǔ)混凝土短柱中的豎向鋼筋或者額外配置受拉鋼筋的方法來傳遞錨栓拉力而避免混凝土崩裂破壞的方法。[關(guān)鍵詞]柱腳錨栓;抗拉強度;ACI規(guī)范;崩裂破壞;拔出破壞中圖分類號：TU391 文獻標識碼：A 文章編號：1002-848X(2013)S1-0436-03Anchor bolts design for tension forceWu Guifang(Tongji University, Shanghai 200092, China)Abstract: By comparing the anchor bolts design for tension force between Chinese code and American code, the various types of steel and concrete failure modes for anchor bolts are presented, and the tension capacity for each anchor bolt failure mode is introduced. In order to avoid concrete breakout prior to anchor bolt steel failure, this paper provide a method to using the vertical reinforcement in concrete pier or add additional reinforcement on both sides of concrete breakout surface to transfer the tension load from anchor bolts.Keywords: anchor bolts; tension capacity; ACI318; concrete breakout; anchor bolt pullout作者簡介：吳桂芳，工程師，一級注冊結(jié)構(gòu)工程師，Email: guifang.wu@hotmail.com。
