摘要

本文报道了轻骨料(Lytag)和碎石混凝土梁在持续荷载作用下的试验。结果表明，轻骨料混凝土梁在持续荷载作用下的挠度和裂缝宽度大于砾石混凝土梁，加载前发生一定比例收缩时，其极限挠度和裂缝宽度小于未发生收缩时。

A comparative study of sustained loading effects on lightweight-aggregate and gravel concrete beams

Tests on lightweight aggregate (Lytag) and gravel concrete beams under sustained loading are reported. It is shown that deflection and crack widths under sustained loads are greater in lightweight-aggregate concrete beams than gravel concrete beams and that when a proportion of the shrinkage had taken place before loading, ultimate deflections and crack widths are smaller than if no shrinkage had taken place.
