Study Of Multi-Ribbed Composite Panel Structure Based On The Building Information Modeling(BIM)Technology

BIM(Building Information Modeling)technology is based on information data from construction engineering,to guide the practical work of construction engineering through the building model integrating with digital information;Multi-ribbed composite panel structure takes a place in construction engineering for its features such as energy conservation and environmental protection,efficient assembly,good structural performance and so on.Both technologies have been widely used in recent years for their significant advantages,but their combination of applications is still blank.To carry out the sustainable development,promote housing industrialization,and promote the integrated application of new technology and new structure system,study of multi-ribbed composite panel structure based on BIM technology is imperative.Adopting object-oriented C#language and the.NET technology combined with Revit API interface and Windows API interface to make secondary development on Autodesk Revit 2016 based on development tool Visual Studio 2015.Generating the multi-ribbed composite wall plug-in system in Revit 2016,which has the type of windows interface and Ribbon style that same as the Revit interface.The main results are:(1)Making humanized software aided design on the multi-ribbed composite wall components such as ordinary multi-ribbed composite wall panel,multi-ribbed composite wall panel with door,multi-ribbed composite wall panel with window and the connecting components in multi-ribbed composite wall panel structure.And make it possible to splice,assemble and implement 3d visualization operating according to the engineering requirements in Revit interface(2)The plug-in system is built in the form of dialog boxes,which is realized data transfer in the building process of components;Through 3D physical model,real-time display technology,Excel spreadsheet data to ensure the friendly and error correction of the aided design technology,ensure the safety and reliability of the structure design.(3)Plug-in system summarizes the material usage of multi-ribbed composite wall components,and verifies the accuracy and practicability of the results by analyzing the example.(4)Plug-in system implements a check design method for the multi-ribbed composite wall,and it can draw the corresponding Nu-Mu curve,which reflects the real-time normal section bearing capacity of wall according to the modeling.The Revit plug-in system draws the Nu-Mu curve for "4×3" ordinary multi-ribbed composite wall as an example,and leaves interface for other forms of wall to draw Nu-Mu curve which is convenient for the follow-up researching and development.
