Bibik M. Strength and deformability of steel elements which undergo tensile with bending taking into account the plastic stage of work

Subject - steel elements with different types of cross section and of stress-strain diagram that undergo tensile with bending. Object - the development of the method of calculation of strength and deformability of steel elements that undergo tensile with bending. Procedures - analytical, numerical and experimental procedures of investigation of building structure deflected mode. Theoretical results - the method of calculation which takes into account geometrical and constructional nonlinearity of these elements as well as precise presentation of steel real diagram is suggested. Practical results - the attained dependencies between cross-section internal forces factors allow to make the engineering calculations of steel elements that undergo tensile with bending more precise and simply in elastic and elasto-plastic stages of work. Innovative: founded scientific conclusions concerning the limit criteria of plastic deformation development for pin-ended steel elements that undergo tensile with bending andconclusions for the effective way of fixing of element's supports. The obtained results were applied during the designing of new and the estimating of deflected mode of existing steel elements that undergo tensile with bending. Field of application - constructional engineering.
