Measurement and Numerical Simulation of Deformation of Pre-Stressed Masonry

Article Preview

Abstract:

Contribution deals with laboratory measurements of deformations in the place exposed to local load caused by additional pre-stressing and its comparison with numerical simulation. The measurements are made at the masonry brick corner built in the laboratory equipment. The laboratory equipment was designed at Faculty of Civil Engineering VŠB – TU Ostrava for measurement tri-axial stress-strain conditions in masonry. The masonry structure of the brick corner is imposed on the vertical load and pre-stress is applied through two bars. The values of deformation from pre-stressing are sensed by potentiometer sensors. Numerical simulation of the brick corner is based on the finite element method using appropriate software and then the results are compared with those of experimental testing. For numerical simulation were used material linearity and material non-linearity of model. On the basis of these results it should be possible to improve the models and come closer to achieving an accurate and at the same time, simple procedure for the design of pre-stressed masonry.
