Abstract

D-REGIONS ARE DEFINED BY ITS NON-LINEAR STRAIN DISTRIBUTION OVER A CROSS SECTION. THE DEEP BEAMS ARE A GOOD EXAMPLE OF D-REGIONS, AS MOST OF ITS LOAD IS USUALLY DIRECTLY DELIVERED TO SUPPORTS. THIS PAPER WILL FOCUS ON AN ALTERNATIVE TO THE WELL-KNOWN METHODS FOR DESIGNING THIS TYPE OF STRUCTURE: STRINGER-PANEL METHOD (SPM). A MANUAL APPROACH OF SPM WILL BE PRESENTED, AS IT HAS A SIMPLE PRINCIPLE OF DIVIDING A STRUCTURE ON TWO DISTINCT ELEMENTS: STRINGERS, WHICH ABSORB NORMAL FORCES, AND PANELS, WHICH ABSORB SHEAR FORCES. TWO PRACTICAL EXAMPLES OF DEEP BEAMS ARE PRESENTED, THE DESIGN OF THESE STRUCTURES IS MADE AND THEY ARE ALSO ANALYZED BY NON-LINEAR SOFTWARE SPANCAD, WHICH IS BASED ON SPM, AND, IN ORDER TO GET A MORE RELIABLE SOLUTION, BY ATENA 2D, WHICH IS BASED ON FINITE ELEMENT METHOD. THIS RESEARCH SHOWED THAT SPM IS A VERY ATTRACTIVE ALTERNATIVE FOR ANALYZING REINFORCED CONCRETE DEEP BEAMS AND RESULTS IN A MODEL AS SIMPLE AS STRUT AND TIE METHOD. MOREOVER, SPANCADÂS ANALYSIS SHOWED THAT ITÂS A USEFUL TOOL FOR DESIGNING AND OBTAINING DEEP BEAMSÂ ULTIMATE LOAD.
