This paper considers L-2-gain analysis for uncertain linear time-invariant systems with polytopic uncertainties interconnected with sector-bounded static memoryless nonlinearities. A finite set of sufficient Linear Matrix Inequalities (LMIs) is derived by leveraging the polytopic structure to compute upper bounds on the system's L-2-gain without requiring gridding or approximation methods. The practical utility of these results is demonstrated through numerical experiments using a benchmark two-mass spring-damper system and a metastructure, exploring relationships among sector bounds, uncertainty levels, and achievable performance.
