Abstract: A response analysis of overground pipelines under multi-compo- nent random ground motion is presented for a parametric study. The pipeline is considered .to be either extended ongitudinally or to intersect and form a T shape. The ground motion is modelled as a stationary random process. Mean square responses of the pipeline are obtained by frequency domain spectral analysis. Res- ponses are also obtained with the help of a quasi-static analysis for random ground motion, for pipelines whose natural frequencies are well beyond the dominant frequencies of excitations. Validity of the latter analysis is examined by comparing its results with those of rigorous dynamic analysis. Distribution of bending moments and axial forces along the length of the pipeline, and at the pipeline intersections are studied for a set of important para- metric variations.
