典型截面 meaning in Chinese

typical section

After the evaluation of the three parameters in the proposed creep model , which is based on the large numbers of experimental measurements of concrete creep , the influential regularities of concrete filled steel tube columns under long - term loading are investigated . by dispersing time , the method of tangent modulus is adopted to study the relation of creep strain and load time . in the end , this paper took cft specimens with representative geometry and sectional dimensions as examples and adopted the proposed method as an approach to investigate the influencing regularities of many factors , which include the ratio of long - term load to strength , the slenderness ratio , the eccentricity ratio , and the intensity grade of concrete , on cft structures
在对钢管混凝土构件长期荷载效应的分析中，本文基于三维粘弹性理论，采用三参数粘弹性模型，提出了核心混凝土徐变的三维有限元分析理论，在总结过去大量关于混凝土徐变试验实测结果的基础上拟合了模型中的三个参数，并成功将其应用于钢管混凝土徐变的三维分析计算中，得到徐变与持荷时间的关系，以典型截面形式的圆钢管混凝土轴压、偏压构件为例，对轴压比、长细比、含钢率、偏心率以及核心混凝土等级分别进行了大量的参数分析和实验对比研究，结果表明二者符合较好。
