| Abstract: | On the computer calculation of bridges, the internal force analysis of space structures often involves the calculation of influence line. But the general methods presently used can not meet the needs of practical engineering. According to the influence line principle, a new and more effective method is given. By creating the relative unit displacement on the concerned node, the influence line principle is employed directly into the practical engineering calculation. The code of our method is written by some ANSYS macros. The results proved that this method can calculate the influence line of the complex structures such as space gridiron successfully and efficiently. |
