Simplified Prediction and Design Applicability of Ground Response Under Multiple-Person Rectangular Excitation

This paper presents a simplified method for predicting ground response under multiple-person rectangular excitation, relevant to large-scale events like concerts. The approach considers geometric distribution, timing offset, and jump landing effects, introducing correction factors for excitation force reduction. Validation using finite element analysis and normal mode solution shows agreement with simulations. The results demonstrate that the proposed method enables practical estimation of ground response, supporting rational design and safety assessment for event venues. This framework provides engineers with an efficient tool for evaluating vibration effects without complex modeling.
