SHARP PC——1500计算机,是一种体积小、重量轻、便于携带、适宜用于工地随时进行桥梁结构验算的微型程序计算机。在用顶推法施工的桥梁工地,用它来随时计算顶推内力,更为方便。本文针对这种计算机的特点,采用Ⅰ_o/Ⅰ图矩面积法计算变刚度连续梁的角变系数,建立三弯矩方程,用追赶法求解。只占用2515字节,就可以满足10余跨变截面连续梁内力计算的需要。本文的主要内容就是使用容量较小的PC——1500计算机,简便地计算比较复杂的变截面连续梁的顶推内力。
SHARP PC - 1500 computer, is a small size, light weight, easy to carry, suitable for site construction at any time checking the bridge structure of the micro - program computer. In the construction site with the push method of construction, use it to calculate the thrust at any time, more convenient. In this paper, according to the characteristics of this kind of computer, I_o / Ⅰ plot area method is used to calculate the angular coefficient of variable rigidity continuous beam, and the three moment equations are established. Only occupy 2515 bytes, you can meet more than 10 cross-section continuous beam internal force calculation needs. The main content of this paper is to use the PC - 1500 computer with smaller capacity to calculate the thrust force of complex cross - section continuous beams easily.
