Abstract: A new finite strip element-hinged plate bending strip element is presented for the analysis of right hinged plate bridges. The corresponding strain matrix, stiffness matrix and load row matrix are derived. Results of numerical examples show that the propoesd methods is adaptable and can be used simply and conveniently for calculation with high accuracy.It opens up a new way for practical calculating and can be calculated by a computer for hinged plate bridges.
