Top 5 Structures Featured in Movies

Structures in movies serve as more than just mere backdrops or settings. They play significant roles in storytelling, providing visual spectacle, symbolism, and often becoming iconic elements of the films themselves. Famous structures like the Empire State Building, the Statue of Liberty, or the Golden Gate Bridge have been featured in films for decades, becoming instantly recognizable and evoking a sense of familiarity. These landmarks serve as visual shorthand, instantly transporting viewers to iconic locations. Moreover, structures can become integral to the plot, driving the narrative forward or acting as the focal point of key events. They can be sites of climactic battles, daring chase scenes, or heroic moments. Check out this list of just a few of our favorites. And maybe these structures will inspire you to watch the films. 1.

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...
