【摘要】 本文以四川省渠县水文站水文缆道设计为例,采用平均参数法进行设计计算,即把钢塔假定为"等钢度、等跨度"的铰链杆件,并以各跨的平均纵向力N和平均支座刚度υ分别代替Ni和υi得出减化铰链法的计算公式。更多还原

【Abstract】 This paper takes the hydrologic station of Qu County of Sichuan Province as an example,introduces design calculation using average parameters,that is assuming steel tower is the gemel member of equal angle,equal span,adopting each span average vertical force N and average bearing stiffness D instead of N1 and D1 to educe the simple gemel method calculation formula.更多还原
