| Abstract: | A dynamic analysis of hybrid masonry-concrete structures encountering the blasting seismic wave is presented. The time-history analysis method of hybrid masonry-concrete structures encountering the blasting seismic wave is set up. Meanwhile, using the blasting seismic wave in a excavating underground workshop of a hydropower plant (Fujian province), a nearby six-floor hybrid masonry-concrete structures were analyzed. Lastly, a security evaluation is made by comparing the results of the dynamic responses under earthquake waves. |
