Abstract

THE T AND K-TYPE PIPE CONNECTORS ARE BEING VASTLY USED IN PLATE AND SPACE FRAME TRUSS, ENERGY TRANSPORTATION TOWERS, METAL SOURCES AND MARITIME PLATFORMS, IN THIS ARTICLE, BY USING THE LIMITED PARTS METHOD, THE PARAMETRIC ANALYSIS OF T AND K-TYPE CONNECTORS WITH SQUARE SECTIONS UNDER AXIAL AND FLEXURAL CHARGES WITHIN THE PLATES WERE CONSIDERED. THE LIMITED SOLID PARTS WERE USED FOR MODELING THE WELDS, AND THE LIMITED SHELL PARTS WERE USED FOR MODELING THE OTHER CONNECTOR AREAS. IN A PARAMETRIC SURVEY, 17 CASES OF THE T-TYPE AND 24 CASES OF THE K-TYPE CONNECTORS WERE METICULOUSLY STUDIED. THE RESULTS OF THESE ANALYSES WERE THE ACHIEVEMENT OF 19 MATHEMATICAL FORMULAE, WHICH INDICATES THE SHOCK CENTRALIZATION RATIO REGARDING THE CONNECTOR’S GEOMETRICAL PARAMETERS. THE ACCURACY OF THESE EQUATIONS WAS SURVEYED, USING STATISTICS SOFTWARE, AND SOME PRECISE RESULTS WERE OBTAINED. IN ORDER TO LOWER THE SHOCKS’ CENTRALIZATION AND TO IMPROVE THE BEHAVIOR OF THE T-TYPE CONNECTORS, THEY WERE REINFORCED WITH REINFORCING CONCRETE OR PLATES AND THE EFFECTS OF THE MENTIONED REINFORCEMENTS ON THE SHOCK CENTRALIZATION RATIO WERE STUDIED. THE RATIONALE OF DESIGNING THE LIMIT CONDITION WAS DESCRIBED BASED ON THE CIDECT AND AWS REGULATIONS, AND AT THE SAME TIME THE EFFECTS OF CHANGING THE ANGLE INHIBITORY PART OF THE Y-TYPE CONNECTOR AND THE GAP BETWEEN TWO SUBSIDIARY PART OF THE K-TYPE CONNECTOR ON THE FINAL STRENGTH OF THE MENTIONED CONNECTORS WERE DISCUSSED THROUGH THE PROKON SOFTWARE. THE COMPLETELY 3D NON-LINEAR ELASTOPLASTIC ANALYSIS OF THE T-TYPE CONNECTORS WAS PERFORMED IN ORDER TO PREDICT ITS FINAL STRENGTH. THE THICKNESS EFFECT OF THE CHORD PART ON THE FINAL STRENGTH OF THE T-TYPE CONNECTORS WAS STUDIED UNDER THE AXIAL CHARGING PRESSURE AND IN THIS REGARD, A MATHEMATICAL EQUATION WAS OBTAINED. THE MENTIONED MATHEMATICAL EQUATION WAS COMPARED TO THE DATA OF THE VALID GLOBAL REGULATIONS AND A FAVORABLE CONFORMITY WAS ACHIEVED. THE LUSAS SOFTWARE WAS USED IN THE NON-LINEAR AND THE ELASTIC BUCKLING ANALYSIS OF THE T-TYPE CONNECTORS. A FIXED OFFSHORE PLATFORMS F9A WAS ANALYZED AND SIMULATED AT THE FORUZAN OIL FIELD AT THE PERSIAN GULF USING THE PROKON SOFTWARE.
