[提要]  高強(qiáng)混凝土柱的梁柱節(jié)點(diǎn)處，以前通常采用澆注少量高強(qiáng)混凝土的方法，樓層梁板則仍用普通強(qiáng)度混凝土。此種方法對(duì)于高流動(dòng)性商品混凝土是很不適宜的。參考國(guó)外多年的試驗(yàn)資料，并根據(jù)新的抗震規(guī)范的精神，提出梁柱節(jié)點(diǎn)的設(shè)計(jì)建議，可供設(shè)計(jì)人員參考。

The method often used for placing concrete of beam-column joints of high-strength columns is to cast a small amount of high-strength concrete in the joint, then to cast the floor slab and beam with normal-strength concrete. Now the ready-mix concrete is very popular in large cities, so we must change the method mentioned above. Considering the ACI code, Canadian code and also several test results, the design recommendations are given for the cases in which the slab/beam concrete is placed through the column.
