The completely overlapped joints of the eccentrically braced offshore jackets were investigated both experimentally and numerically. A full-scale specimen was tested under cyclic quasi-static loading. In test, local buckling first observed around lap brace through-brace intersection. crack then developed at weld toe between through brace, propagation led to final failure joint. Indicators assess performance evaluated within context seismic resistance. energy analysis indicated that...
This paper presents the development of a parametric equation for predicting ultimate capacity tubular circular hollow section joint with complete overlap braces based on experimental and numerical investigation. In experiment, specimen is tested to failure under lap brace axial compression verification finite-element (FE) model. The comparison results showed that FE model simulates very well current previous test specimens differences in displacement less than 1.52 3.5%, respectively. study,...
A full-scale uniplanar completely overlapped tubular K(N) joint specimen is tested to determine the hot spot strains at intersections for verification of finite-element (FE) model. The test results reveal that maximum strain concentration occurs on through brace saddle near lap brace. On chord, distributions perpendicular weld toes are linear but and brace, they nonlinear. Based FE analysis results, effects geometric parameters stress factors (SCF) found most crucial. use existing Y-joint...
This paper presents a set of parametric equations for predicting the stress concentration factor (SCF) at crown toe, saddle, and heel completely overlapped tubular circular hollow section joints under lap brace axial compression. In study, joint specimen is tested within elastic limit steel material verification finite-element (FE) models. The comparison results showed that 8-node thick shell 20-node solid FE models simulate reasonably well test with average difference in strain (SNCF) 7.9...
An eccentric jacket substructure is comprised of circular hollow section tubular joints with complete overlap braces. The joint formed the lap brace overlapping diagonal through joining chord face. In this study, subjected to a static vertical load due self-weight and facilities, four horizontal loads simulate environmental applied at different angles. maximum stresses each level are found lower than that traditional jacket. For substructure, high stress critical area mostly located short...
Filter systems are widely used in petrochemical plants for removing solid impurities from hydrocarbon oils. The backwash is the cleaning process to remove on sieves of filters without a need interrupt operation entire system. This paper presents case study based actual project filter system plant, demonstrate significant effect vibration structural integrity piping. induced had led fatigue failure pipes connecting A preliminary assessment suggested that vibrations caused by backwashing...
The upsizing and rapid development of container ships has resulted in many large launching small slipways due to the lagging advanced equipment. In particular, dynamic characteristics these longitudinal operation under restricted water are yet be studied detail. this study, a ship model simulate process an 8500 TEU was created based on URANS method. resistance calm determined validated against experimental data. influence stern appendage ship’s flow field around hull, with without aft...
