【摘要】 该试验是为了研究钢筋混凝土的强度和刚度,主要测定其强度、安全度、抗裂度及各级荷载作用下的挠度和裂缝情况,另外就是测量控制区段的应变大小和变化,找出刚度随外荷载变化的规律。更多还原

【Abstract】 This paper studies the strength and stiffness of reinforced concrete,mainly measures the strength,safety degree and crack resistance of reinforced concrete and the deflection and development of cracks under different load levels,and measures the sizes and variations of the strains within the control section,and finds out the rules that the stiffness changes with the variation of external load.更多还原
