Weak Story Solutions

We design and manufacture high performance steel moment frames using our patented technology. With all parts bolted together on site without any field welding, our solutions are very practical and cost effective.

We use very compact member sizes to hide steel members into walls and ceilings to maximize clear span and height:

• W10x45 Special Moment Frame
• W10x68 Spiecial Moment Frame
• One-Story Ordinary Moment Frame





Patented Connection Technology

This revolutionary steel connection utilizes three dimensional connection plates in a simple and consistent manner, and is suitable for all possible connection configurations that are made of steel I-beams. With a very unique load transferring path around the envelope of a joint, the patent technology removes all interior constraints and releases stress concentration status, so as to dramatically improve overall ductility of the connection. Since all components and parts can be prefabricated in shop, it can be conveniently bolted together at field without field welding. In brief, this high performance connection eliminates the inherent drawbacks and problems of conventional bolted and/or welded connections, and is very suitable for steel moment connections in general, as well as weak story retrofit in particular.
