Influence on crack development in concrete structures from imposed strains and varying boundary conditions

Pettersson, Dan; Alemo, Jan LU and Thelandersson, Sven LU (2002) In Construction and Building Materials 16(4). p.207-213
Abstract
Crack development due to imposed strains in different types of concrete structures and with varying boundary conditions is studied in order to improve control of cracking. A previously developed two-dimensional FE-method is used, with closing forces in cracks concentrated to spring elements. Temperature changes are used as load, and the calculations are performed stepwise with opening of nodes and implementation of spring elements. The FE-method has also been used to study crack widths and crack spacing for a wall fully restrained at the bottom. It is shown that the type of restraint has significant influence on crack widths. For structures with restraint along the length direction the restraint effectively facilitates distribution of... (More)

The FE-method has also been used to study crack widths and crack spacing for a wall fully restrained at the bottom. It is shown that the type of restraint has significant influence on crack widths. For structures with restraint along the length direction the restraint effectively facilitates distribution of cracking, similar to a wall fully restrained at the bottom.
