预应力混凝土预制梁在存梁期内因温度变化而产生挠度。本文导出以预制梁在日照和日气温变化作用下的挠度计算公式 ,并列出算例 ,计算值与实测值接近
Prestressed concrete prefabricated beams in the storage period due to temperature changes and deflection. In this paper, the deflection formula of prefabricated beam under sunshine and daily temperature change is deduced, and the calculation example is given. The calculated value is close to the measured value
