Abstract: Great parts of ship construction and steel girder bridge are consisted of plate structures, such as stiffened plates and plates with lightning holes. In application of welding and gas cutting to fabricate them, the shrinkage of heated portion may usually produce distortion and residual stresses in each element of plate structure. Such initial imperfections may be decisive factors for structural strength and ultimate strength of plate structure subjected to compression. The purpose of this study is a investigation of the relation between ultimate strength and initial imperfections of stiffened plates and plates with a hole subjected to in-plane compression which are consisted of comparatively thick plate as used for ship construction. In part 1., the ways of experimental and numerical analyses of plate structure are shown. The deformation and the stress distribution in each structural element are calculated by the finite element method based on incremental theory. And the propriety of analytical method is examined by comparing with measured values on a few experimental model.
