May 3. I began with my Saw, and cut a Piece of a Beam thro', which I thought held some of the upper Part or Quarter-Deck together, and when I had cut it thro', I clear'd away the Sand as well as I could from the Side which lay highest; but the Tide coming' in, I was oblig'd to give over for that Time.

针对施工期现浇钢筋混凝土结构的时变性，定义楼板刚度与模板支撑的刚度比为施工时变结构体系的弹性特征值，建立了以施工时变结构体系弹性特征值为参数的现浇钢筋混凝土结构施工受力性能分析的弹性支撑连续梁模型，基于该模型，分析了施工期现浇钢筋混凝土结构的受力特性，发现在特定施工方案下，当施工时变结构体系的弹性特征值较小时，最大施工荷载出现的楼层位置会提前，而拆模时间也会改变最大施工荷载出现楼层的位置；施工时变结构体系的弹性特征值和拆模时间都影响楼层承担的最大施工荷载比率(荷载比率定义为结构承担荷载与楼板自重的比值)；施工期楼层承担的最大施工荷载随楼层位置呈现波动特性，随楼层位置增高波幅逐渐减小，最后趋于稳定。
