| Abstract: |
Floods and undermining have analogous destructive effects on building structures and decline their lifetime. Load may also result from impeded strain of historical concrete and masonry structures. The paper reports the design of the FEM model for solving interaction between foundation and subsoil. Influence of groundwater level changes on settlement and tensile stresses of structures are taken in account. Settlement of structure with changes of mechanically - physical properties of subsoil, and cracks in masonry and foundation structures are various damages. Cracks and tensile stresses may be eliminated by prestress and grouting. Comparison of Czech and European standard specifications for solving interaction problem, examples of strengthening and static provision of cracked historical buildings and extension their service life are presented. |
