Finally, the software is validated through the example and a dynamic response instance of the laneway under the seismic load is given out.
The emphasis of the design-concept of these new measures is they don't resist seismic load by enforceable measures but allow their failure or damage for the bridge safety.
According to the relationship between the structural strength and slenderness of plate elements, the limited width-to-thickness ratio of the flange of a box-section column under seismic load is derived.
The loading process is designed on the basis of the cracking and yielding loads and earthquake action as calculated for seismic load of fortification intensity.
The dynamic response of the structure under seismic load is calculated by the program. The critical value is attained according to the rule of B-R and dynamic response of the structure.
Moreover, the loosened rock mass of the steep slope has the overturn risk under seismic load.
