Hi, I'm Onur CEYLAN, I bought IdeCAD Static 6 version last week. While solving a project, I entered the basics constantly. When I want to get a report as a result of the analysis, it gives 6 negative ground safety errors. When I look at the foundations from the Reinforced Concrete-Continuous Foundation button, I see that it saves the ground safety value. Since there are no errors in the reports, these 6 continuous foundations give errors, what should I do to avoid these errors in the report. I am waiting for your answer to solve my problem as soon as possible. Take it easy, best regards...[ /quote] Hi, It's hard to answer without examining your project. However, there are some possibilities: 1. The soil problem is indeed there, but the program may not show the problem in the reinforced concrete dialog 2. The soil problem is not really there, but the program may show a problem in the output. For both cases, the ground safety problem I suggest you to look at the options related to the control control.In the analysis settings: 1. Negative tensile Are you checking me? 2. Have you marked the average strain? 3. Have you taken into account the effects of earthquakes? 4. Are the tolerance values zero or did you enter any value? You can pinpoint the problem by trying the reverse of these conditions. Take it easy, good work...
