Abstract : based on the principle of mininmum potential and using rayleigh - ritz method , the geometric non - linear analysis of higher bridge piers was solved in this paper . the new concept of equivalent horizontal force proposed by the author may be casily to calculate the second effect , which was produced due to the vertical forces and resisted by the piers and rubber pad bearings incorporately . the simple formula in this paper are applicable to calculate by hand , understood clearly without computation of successive iteration , higher precision and graspable easily for the disigmer therefore it has the practical significance 文摘:根據最小勢能原理,用瑞雷-里茲法解決了高橋墩的幾何非線性分析問題;其次,提出了等效水平力的新概念,可以方便地解決橋墩和板式橡膠支座聯合抵抗垂直力所產生的二次效應問題.筆者提出適合于手算的簡便計算公式,概念明確,勿須迭代運算,精度較高,易為設計人員掌握,因此具有實用價值
