The average compressive  strengths  of  concrete cylinders (100 × 200 mm) are presented in Table 1。 The concrete cylinders were tested on the 36th day after concrete casting。 The column specimens were tested on the 34 ∼ 36th days。 As mentioned, in square-section Specimens E1, E3, and E4, the compressive strength of the concrete was fc0 ¼ 70。5 MPa。 In the rectangular-section Specimens E2 and E5, the concrete strength was fc0  ¼ 83。6  MPa。 薄壁矩形混凝土填充管(RCFT)柱英文文献和中文翻译(4):http://www.youerw.com/fanyi/lunwen_81804.html
