（合肥工業(yè)大學(xué)建筑工程系 230009）[提要] 在國內(nèi)外研究的基礎(chǔ)上，設(shè)計(jì)了兩個(gè)無粘結(jié)預(yù)應(yīng)力扁梁邊柱節(jié)點(diǎn)試件，并進(jìn)行了低周反復(fù)加載，對試件的破壞過程和破壞形態(tài)、試件的承載力及剛度退化、延性與耗能、應(yīng)變分析等問題進(jìn)行了研究。提出了實(shí)用的設(shè)計(jì)建議和配筋構(gòu)造措施。
[關(guān)鍵詞] 預(yù)應(yīng)力混凝土 扁梁節(jié)點(diǎn) 反復(fù)荷載Two wide-flat beam-column joints under the low reversed cyclic loading were tested to investigate the
following properties: failure process and failure state, strength stiffness reduction, ductility, energy dis-
sipation, analysis of strain of non-prestressed bars and prestressed tendons, etc. Based on the results of the tests, some recommendations are presented.
Keywords: unbondod prestressed concrete; flat beam-column joints; reversed loading
