COARSE GRID SANDWICH CONSTRUCTION FOR WELDED STEEL STRUCTURES

BECAUSE OF THE MANY INNOVATIONS BEING MADE IN THE DEVELOPMENT OF MATERIALS AND IN FABRICATION AND CONNECTION TECHNIQUES, SANDWICH CONSTRUCTION FOR WELDED STEEL STRUCTURES MAY SOON BE FEASIBLE. METHODS OF ANALYSIS ARE DISCUSSED ALONG WITH A FABRICATION METHOD THAT MAY LEAD TO ECONOMICAL SOLUTIONS. THE COARSE GRID SANDWICH AS DEFINED HERE CONSISTS OF A RELATIVELY COARSE PATTERN OF STEEL BARS FRAMED AND SANDWICHED BETWEEN TWO SHEETS OF STEEL. THIS GENERAL TYPE OF SANDWICH IS PARTICULARLY WELL SUITED FOR WELDED STRUCTURES NOT ONLY BECAUSE OF THE LIKELIHOOD OF THE EXISTENCE OF HIGH SHEAR AND BENDING CONDITIONS BUT ALSO BECAUSE QUALITY OF CORE MATERIAL CAN BE CLOSELY CONTROLLED; SHEAR STRENGTH OF THE CORE CAN BE DESIGNED FOR ANY DESIRED VALUE; AND THE CORE CAN BE LOCALLY REINFORCED AND ITS ARRANGEMENT AND ORIENTATION ALTERED TO SUIT A GIVEN DESIGN. IN GENERAL, SANDWICH MATERIALS CAN BE USED EFFECTIVELY WHERE EITHER LOCAL OR GENERAL INSTABILITY DOES NOT ALLOW THE FULL UTILIZATION OF THE STRENGTH OF CONVENTIONAL MATERIALS. A FEW OF THE POSSIBLE APPLICATIONS IN CIVIL ENGINEERING STRUCTURES WOULD INCLUDE GIRDER WEBS, FLOORING SYSTEMS, BOX GIRDERS, BUILT UP COLUMNS, LOAD CARRYING WALLS, BRIDGE DECKS AND FOLDED PLATES. /AUTHOR/
