一、前言单柱日照变形,指的是独立高柱在空间受阳光照射,向阳面温度高,背阳面温度低,而产生了温度差,致使高柱向阳面膨胀引起高柱上半部向着背阳面弯曲位移变形。众所周知,一般物体均有热胀冷缩的特性,钢筋混凝土柱亦不例外(其材料的线膨胀系数为1.08×10~(-5)),对于钢筋混凝土柱,特别是多层装配式的钢筋混凝土柱的垂直度有
I. INTRODUCTION Single-column solar radiation deformation means that an independent high column is exposed to sunlight in the space, the sunny surface temperature is high, the back surface temperature is low, and a temperature difference is generated, resulting in expansion of the high column to the sunny surface causing the upper column to move toward the back Yang surface bending displacement deformation. As we all know, the general objects have the characteristics of thermal expansion and contraction, reinforced concrete columns are no exception (the linear expansion coefficient of the material is 1.08 × 10 -5), for reinforced concrete columns, especially multilayer assembled steel The verticality of the concrete column
