Background: Risks and mechanisms of extension of conservatively managed spontaneous coronary artery dissection SCAD remain incompletely understood.
Study objectives were to 1 evaluate mechanisms of early SCAD evolution through serial angiographic analysis, and 2 determine predictors of early SCAD progression. Patients who experienced significant SCAD progression within 14 days, defined as clinical worsening plus new critical coronary obstruction on repeat angiography, were compared with remaining controls. A total of 42 of For example, FE that simulates node flexibility, FE that simulates the work of the ground outside the structure, FE that simulates the tensioning device turnbuckle and allows you to provide the specified initial tension of the structure contour or to find the necessary tension that ensures the specified geometry e.
This solver enables you to simulate assemblage of high-rise buildings from monolithic reinforced concrete with account of seasonal variation of material concrete properties, disassemblage of temporary supports, climate variation, etc.
The set includes drawings of element layouts, lists of elements, joints, bill of materials. Then it is possible to calculate moduli of subgrade reaction that are variable across the foundation slab.
This enables you to take into account: 1 change in stiffness of soil under dynamic loads including earthquake , and 2 exclusion of separate elements from design model when analysing problems of progressive fracture. LIRA software is continually updated to include new programs and enhance features of existing ones. New versions of the program appear routinely, they support new operating systems, include new options and systems, and take account of new generation of CAD programs.
Every new version contains Installation Guide, Tutorial, and extensive Help system where you can find detailed information about options and tools of the program. Our Technical Support Team will help you find answers to your questions or resolve any concerns you may have about one of our products. It is possible to perform analysis of the whole structure or its separate parts and generate working drawings and reinforcement patterns for structural elements.
These modules are integrated but they may work in stand-alone mode as well. Model of the structure is generated from structural elements STE. Loads are collected automatically, sections of structural elements can be determined and checked. You can generate 3D design model of the structure, perform finite element analysis and evaluate analysis results. Loads are collected automatically, sections of structural elements can be determined and checked.
You can generate 3D design model of the structure, perform finite element analysis and evaluate analysis results. Bill of materials is generated. Analysis and design of reinforced concrete elements. Analysis results in the form of working drawings. DXFfile of the drawing and text files of reports are generated. All modules contain extensive help system where you can find detailed information about options and tools of the module.
You can create and analyse design models of the structure in the shortest possible time and produce fully detailed reinforced concrete drawings with minimum effort.
