1. Introduction The Sumo Workshop is aimed at deepening your understanding in the use of Sumo. Although there is a default workflow to this course, your own examples are encouraged.
Note: The original Sumo training is a prerequisite for this course.
2. Purpose of this course The support staff and trainers at PROKON have worked together to compile a list of topics that users regularly ask about. This course has been compiled to address most of these regular issues that users face. Sumo is PROKON’s flagship analysis program a nd contains a lot of functionality. Although the Sumo training covers Sumo’s functionality, some tools need more attention than other . This course doesn’t address anything new. Rather, we aim to strengthen your knowledge and application within Sumo. 3. Methodology The course is set up so that there is active participation by attendees. A list of predefined Sumo models will be used to point out certain topics that must be addressed. In some cases, the analysis isn’t successful until errors are addressed. In other cases, the tools in Sumo are used to show important information about the analysis.
Although this document contains the answers to all the provided Sumo models, please attempt to solve the problems first.
4. Answers
4.1 No supports Single column with loading, no support.
A structure must have supports before the analysis is attempted.
4.2 No rotational supports Single column with loading and Pinned support.
A model must have supports to restrain all 6 degrees of freedom, even if no results are expected for a certain support condition.
4.3 Unstable structure Beam pinned at both ends, columns have pinned supports.
The beam element’s end conditions have torsional fixities, and there is no rotational support about the X-axis. The structure is numerically unstable.
4.4 Pinned column, pinned support Column start fixity is pinned; connected to pinned support.
A pinned support in conjunction with a pinned end condition causes a numerical instability. There are, essentially, two pins connected to each other.
