Our Portland office is pleased to announce two recent additions to their team, Kolby Sniff and Casea Peterson.
Over the past few decades, earthquake knowledge and understanding has seen significant progress through scientific advancement, research and testing, and investigating the performance and failures of existing structural systems following major earthquakes. This progress has allowed building codes to further evolve by providing stricter requirements and requiring more resilient structural systems for addressing seismic safety in new buildings. Technology has also played a key role by allowing structural engineers to build advanced computer models that predict seismic behavior of buildings more accurately, and produce more robust structural systems for earthquake protection.
New buildings and those constructed more recently have already realized the benefits of this progress, however there are still many existing buildings in use with varying levels of seismic deficiencies that present a risk to life safety depending on the era they were constructed. Despite these issues, most national and local building codes do not require that existing buildings are brought to comply with current code for seismic requirements unless there is a change to the building that triggers a seismic upgrade.
During the design process, it’s essential to consider the anticipated structural load of a project.
Loads are commonly understood as forces that cause stresses, deformations, or accelerations. These loads are applied to a structure or its components that cause stress or displacement.
There are many types of structural loads that you need to account for during the design process. And some – like live loads – present specific challenges that require a deeper understanding to conceptualize.
Nishkian Dean is proud to have provided Hensel Phelps and the United Launch Alliance with their engineering consultation services in support of the NROL-65 launch mission on August 28th. Congratulations to all of the team members who helped make the launch of Delta IV Heavy a success!
