【摘要】 在金山大厦预应力钢骨混凝土转换梁内埋设钢弦式应力计进行施工全过程跟踪实测 ,实测结果与设想结果之间存在显著差异。理论分析表明 ,转换层上部结构超过一定高度后 ,考虑混凝土收缩和徐变引起的转换梁应力下降的理论值与实测值吻合较好。并对转换梁的长期跟踪实测和分析提出了建议。更多还原

【Abstract】 The prestressed steel R.C. transfer beam of Jinshan mansion was tested during the whole construction procedure with the steel chord stress meters held in predetermined positions. Through theoretic analysis, the reason was found to explain the great differences between the test results and predicting results. Some suggestions were put forward about testing and analyzing of transfer beam.更多还原
