摘要

本文通过五根低配筋两跨连续梁的静力试验

研究了连续梁弯矩调幅后的内力重分布规律

详细分析了弯矩调幅对低配筋连续梁使用荷载阶段裂缝宽度和挠度的影响

其结论可供编制内力重分布设计规程参考。

Abstract

Through the static tests of five two-span continuous beams with a relatively small steel ratio

the regularity of redistribution of internal forces of continuous beams with moment modulation is studied

and the moment modulation influence on cracking and deflection of continuous reinforced concrete beams under service loads is analyzed in detail. The conclusions obtained may be used as reference materials for drafting of design code considering redistribution of internal forces.
