In order to study the behavior of r . c . columns subjected to biaxially eccentric loading , the l - shaped column of three sets of steel ratios was calculated . according to the results calculated by the program ( asc ) , the behavior of loading response was investigated 為了研究異形截面柱的在雙向偏心受壓下的受力及變形規律,本文利用程序asc對三種不同配筋率下的l形柱進行了分析、比較,總結了異形截面柱的受力及變形規律。
4 experimental researches on l - shaped columns are conducted , the results agree well with theoretical ones . it approves that for l - shaped columns , the ductility is truly bad when web is in compression . though axial compression ratio takes 0 . 536 , bad ductility results 4對l形柱軸壓比問題進行了試驗研究,試驗結果也證明了數值計算結果的正確性,證明l形柱當腹板受壓作用時延性的確很差,即使軸壓比取0 . 536延性都很差,提出對柱軸壓比要求較嚴的結構,不宜采用l 、 t形柱。
