Removal of local extremes and averaging of local forces in slabs in SCIA•ESA PT | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Probably every civil engineer who ever designed plated reinforced concrete structures came across the problem of local extremes of internal forces in slabs that occur in the location of local supports and at the ends of load bearing walls. These extremes follow from the principles of the finite element method and are unrealistic; even though they affect only a small vicinity of the local supports, they degrade the calculation results. They (these extremes) appear in graphical and text outputs, influence the search of extreme values, etc. Moreover, these unrealistic values are applied also in the calculation of required reinforcement areas and in checks of plates and walls, which may lead even to a failure of the calculation algorithm, as technical standards do not assume such extreme values. SCIA•ESA PT introduces new tools for the reduction of these extremes: averaging areas and averaging strips. Both the tools provide for averaging of internal forces (bending moments, shear and axial forces) over the width of the defined rectangular area or strip. These averaged internal forced are displayed on the screen and in the document and, naturally, are used also as input data for the calculation of required reinforcement areas. The user specifies the averaging areas or strips after the calculation and can immediately review the change in the internal forces. This enables him/her to adjust the width of the area interactively and analyze its influence on the size of e.g. hogging moments. The images clearly show that the range of banding moment mx decreased from <-185, 38> to <-82 , 36>. The averaging strips are a part of the basic module and can be used for the design of plated and plate-wall structures according to all national technical standards implemented in SCIA•ESA PT. |

Recruitment, SCIA innovates | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Today recruiting a good engineer in Belgium and Holland has become a real challenge. SCIA, continuously seeking for new talents, is well aware of this situation. The discussions with our customers are also often directed towards this subject: there really is a shortage of engineers in our sector, which also implies that real evolution possibilities turn up, in particular at SCIA. So as to go beyond the traditional recruitment procedures (advertisements, Internet site, publicity and head-hunters) SCIA applies the Belgian motto: "together we are strong". To achieve this, we propose our customers and partners to publish their job offers on our site. As professionals of the construction world frequently visit our site, they will be able to find a whole range of vacancies for all kinds of profile types and ambitions. It is already possible to publish your employment offer on our site or consult the ones which are already on line, on the address: http://www.scia-online.com/en/careers.html |

Tips & Tricks: Picture Rendering in the Document in SCIA•ESA PT | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
When viewing a structure in the general environment, it is possible to show the surfaces of the structure and to render these surfaces using the respective buttons in the Command Line. For 1D members it is required to first activate the surface because if no surface is activated, nothing can be rendered. For 2D members this is not required since a 2D member by default ‘is’ a surface. This same idea is used in the document. When a Wired view of a structure is sent as a picture to the document, the properties of the picture can be edited using the Properties Window: When the Display mode is changed from Wired to Rendered, nothing happens: the rendering is activated however the surfaces are not yet visible. The solution is thus to activate the Member surface through the Structure tab of the View Parameters. After activating the surfaces, the structure is shown with its rendered surfaces: It is important to keep this in mind since the applied procedure does not require the user to exit the document: all picture manipulations can be done through the Properties Window. |
