COLUMNS WITH AND WITHOUT TENSILE STRENGTH. AN EXTENSION OF THEORIES USED FOR THE COMPARISON OF DEFLECTIONS, ROTATIONS, STRESSES AND STABILITY

PELARE MED OCH UTAN DRAGHAALLFASTHET. EN UTVIDGNING AV TEORIER SOM ANVAENDS FOER JAEMFOERELSE AV NEDBOEJNINGAR, VINKELAENDRINGAR, PAAKAENNINGAR OCH STABILITET.

THE THEORY RELATING TO STRUTS WITHOUT TENSILE STRENGTH WHICH CAN CARRY A VERTICAL LOAD BUT ALSO A HORIZONTAL LOAD IN COMBINATION WITH A VERTICAL LOAD, HAS BEEN DEVELOPED SINCE THE MIDDLE OF THE 1950'S. THE STATEMENT THAT THE STRUT HAS NO TENSILE STRENGTH IS DISCUSSED IN THIS REPORT. THE SHEAR STRESSES AND TENSILE STRESSES WHICH ARISE ARE CALCULATED IN A PRACTICAL EXAMPLE WHERE THE STRUT IS SUBJECTED TO A HEAVY LOAD. A COMPARISON IS MADE BETWEEN STRUTS WITH AND WITHOUT TENSILE STRENGTH WITH RESPECT TO ROTATION AT THE END, MID- HEIGHT DEFLECTION, VERTICAL SETTLEMENT AND EXTREME FIBRE STRESS AT THE EDGE IN COMPRESSION. THE RATIO OF THE MIDHEIGHT DEFLECTIONS INCREASES PARTICULARLY RAPIDLY, WHILE THE ROTATION AT THE END WHICH IS DECISIVE WITH REGARD TO INTERACTION WITH OTHER STRUCTURES, IS RELATIVELY CONSTANT IN THE REGION OF INTEREST. INTERACTION WITH A HORIZONTAL STRUCTURE UP TO STABILITY FAILURE IS ELUCIDATED IN ONE LOADING CASE. THE REPORT SHOWS HOW A SOLUTION IS FORMED FOR A STRUT IN COMPRESSION DUE TO A TRANSVERSE POINT LOAD.
