Curved façades can help create architecturally appealing steel structures and may even reduce the effects of wind loading. However, careful coordination is needed between engineers, contractors and glaziers when locating façade attachments. Providing adequate tolerances and avoiding field fixes can prove to be more challenging for curved façades than for conventional rectangular ones.

Developing High-Capacity Tension Straps for Mass Timber Engineering
Mass timber buildings use cross-laminated timber (CLT) or mass plywood panels to create horizontal diaphragms to transfer wind and seismic forces into the vertical elements of the lateral-force-resisting system. Spline connections resist shear forces at the panel joints, which I discussed in this blog post. I wanted to discuss several options for tension straps used for chord splices and collector forces. This blog will not discuss methods for calculating design forces. Instead, I am going to focus on several strap products and how we developed their allowable loads.
Simpson Strong-Tie® Yield-Link® Moment Connection Case Study: Rose Avenue Elementary
Structural engineers for the Rose Avenue Elementary School project in Oxnard, California, a high seismic zone, chose to switch from special moment frames requiring welded connections to the Simpson Strong-Tie Yield-Link moment connection, which features bolted connections instead of onsite welding. This case study shares the experiences of structural engineers, fabricators and other project partners utilizing this innovative solution for structural steel construction.
Simpson Strong-Tie Engineer to Talk on Mass Timber Construction and Design
Simpson Strong-Tie is proud to announce that one of our product engineers, Bonnie Yang, Ph.D., P.E., CFS, has been invited to give a public lecture on mass timber connections. The date of her lecture will be March 3 at 11 a.m. PST. Yang’s lecture will be part of a Mass Timber mini-lecture series hosted by the School of Architecture at Mississippi State University in partnership with the Mississippi Forestry Association.
