The random vibration approach is theoretically superior in dealing with such multiple excitation problems , however it has hardly been practically applied due to its computational complexity , in addition to the problems relating to its input and output 随机振动法在处理这类问题时理论上有很大的优越性,但在国内外地震工程中还几乎没有获得实际应用,主要原因之一就是计算复杂性。
The pseudo excitation method ( pem ) has brocken its efficiency - bottleneck , and appears to be quite effective in coping with such multiple excitation random analyses . therefore introducing the random vibration approach into the bridge engineering as a tool of seismic designs not only meets the objective requirement and the modem technological development , a good methodology background is also available 虚拟激励算法突破了计算效率瓶颈,并且易于处理多点激励问题。因此,将随机振动法作为一种新的桥梁抗震设计方法引入我国桥梁工程界不仅符合客观需求,体现了设计水平的现代发展趋势;而且在方法论上也有了比较有利的条件。
