 In this study , the dynamic unstable phenomenon and critical load variation of the spatial truss under the beating - wave load were researched . For this purpose , a non - linear governing equation of a shallow spatial truss was derived . In addition , a dynamic analysis and a characteristic analysis of the buckling phenomenon were conducted using the numerical method . The analysis model was selected considering the number of free nodes and the rise - span ratio , and the response to the periodic parameter that determines the period of the beating function was analyzed . To compare the results , a analysis for the step load and sinusoidal - wave load were also conducted . Resonance was observed in the analysis results for both the sinusoidal - wave load and the beating - wave load . The patterns of critical load level were similar in the area lower than the natural frequency , but they were different in the area above it . Furthermore , the critical level of the beating - wave load changed more sensitively than the sinusoidal - wave load did and was much lower than the step load .
