DEVELOPMENT OF A GENERALLY VALID METHOD OF CALCULATING CRACK WIDTHS FROM APPLIED STRESS, BASED ON THEORETICAL KNOWLEDGE AND THE RESULTS OF TESTS

项目名称：	DEVELOPMENT OF A GENERALLY VALID METHOD OF CALCULATING CRACK WIDTHS FROM APPLIED STRESS, BASED ON THEORETICAL KNOWLEDGE AND THE RESULTS OF TESTS
摘要：	THE EXISTING CHECK PROCEDURE FOR RESTRICTING CRACKING IN DIN 1045 LEADS IN A LARGE NUMBER OF CASES TO RESTRICTIONS IN CONSTRUCTION PRACTICE. THESE RESTRICTIONS ARE BROUGHT ABOUT BY THE TYPE OF CHECK AND NOT BY SAFETY REQUIREMENTS. OTHER CHECKING PROCEDURES - FOR EXAMPLE CEB PROPOSALS, BRITISH STANDARD, AMERICAN DESIGN PROPOSALS ETC - ALSO BRING ABOUT SIMILAR RESTRICTIONS IN USE. THE BASIC FACTORS WHICH DETERMINE CRACKING ARE WELL-KNOWN. THERE IS A NEED TO DRAW UP A FORMULA FOR CHECKING CRACK WIDTHS IN SUCH A WAY THAT ENGINEERING INFORMATION FOR ALL FIELDS OF APPLICATION IS RELIABLY DETERMINED. AFTER A GENERALLY VALID FORMULA HAS BEEN DEVELOPED A SIMPLER DESIGN PROPOSAL CAN BE DERIVED FROM THIS.
