An Simple and Easy Way to Obtain Reactive Force from Bearings of Ordinary Single Span Skewed Beam Bridge with Dense Ribs and Bearings

用ANSYS实体单元建模计算分析了斜梁桥恒载支座反力规律,从中提出了提取斜梁桥恒载支座反力的简便快速计算方法,并用ANSYS验证了桥梁博士梁格法的准确性。在此基础上,用桥梁博士梁格法分析了斜梁桥活载反力规律,并提出了提取斜梁桥活载支座反力的简便快速计算方法。该方法在实际工程中很大程度提高了工作效率。

A model established with solid elements on ANSYS is used for calculation and analysis of the rule of the reactive force from the dead load bearing of the skewed beam bridge, from which a simple and fast way is proposed to calculate that force. ANSYS is also used to verify the correctness of the grillage method by Dr. Bridge, based on which, that method is used to analyze the rule of reactive force of live load on the skewed beam bridge, with the proposed simple and fast method for calculation of that reactive force. The method has greatly raised efficiency in practical works.
