Engineering Tomorrow: Transforming Engineer-Draftsman Teamwork with BIM

In the realm of construction and architecture, the role of structural engineers and draftsmen has undergone significant transformation. Traditionally, structural engineers and draftsmen worked in somewhat separate spheres, with draftsmen focusing on detailed drawings and engineers concentrating on structural integrity and calculations. However, the advent of Building Information Modeling (BIM) has brought these disciplines closer together, fostering a more integrated approach to design and construction. The Traditional Divide Historically, draftsmen were responsible for producing detailed technical drawings based on the structural engineer's specifications. This often led to a disconnect between the conceptual and practical aspects of the design. Engineers would provide the necessary calculations and specifications, which draftsmen would then translate into detailed plans and blueprints. This linear process, while effective, sometimes led to inefficiencies and errors due to miscommunication or misunderstandings. The BIM Revolution Building Information Modeling (BIM) represents a paradigm shift in how design and construction projects are managed. BIM is a digital representation of the physical and functional characteristics of a project. It is more than just a 3D model; it integrates various data sources and provides a collaborative platform for all stakeholders involved in a project. For structural engineers and draftsmen, BIM has revolutionized their working…

Why Do Seismic Brace Story Forces Change My Existing Code Checks?

It is possible for seismic (OCBF or SCBF) vertical braced connections to have some limit state code checks lower than those for the same non-seismic connection.

Importing Recorded Seismic Ground Motions

The Pacific Earthquake Engineering Research center (PEER) has a large library of measured earthquake records. Below is an example of how to quickly convert one of these records into a format that can be imported into RISA.

Making a Time History Animation Video

Time history analysis solves for normal analysis results (joint displacements, member forces, code checks, etc.) based on loading that varies with time. For some analyses it may be useful to view an animation of the deflected shape of the structure as a function of time. This blog topic serves as a...

What Loads Transfer from RISAFloor to RISA-3D?

RIAFloor designs the gravity system and then integrates with RISA-3D to design the lateral system. Only the lateral members are taken from RISAFloor over to RISA-3D. The loading is automated in this integration so one of the most common questions is: what loads are transferred when switching from...
