Dynamic Response of Shell-like Hyperbolic Paraboloid (HP) Concrete Beams: Comparing Experimental Modal Analysis (EMA) with Numerical Finite Element Analysis (FEA)

Paper i proceeding, 2026

This paper examines the dynamic response of shell-like hyperbolic paraboloid (HP) shaped concrete beams. It compares experimental modal analysis (EMA) results with finite element analysis (FEA) and Euler-Bernoulli beam model results. It presents a case study involving a 3x0,6-meter steel reinforced, non-prestressed HP concrete specimen. EMA based on a roving hammer test provides the first six eigenfrequencies and mode shapes along with modal damping ratios, which are evaluated against numerical results.
