Simpson Strong-Tie® Composite Strengthening Systems (CSS) are designed, tested and manufactured to offer high-performance solutions and lasting results. CSS products are efficient fiber reinforced polymer (FRP) strengthening solutions used to increase or restore the load-carrying capacity, ductility, and seismic resistance to a variety of structures.

State-of-the-art composite strengthening systems meeting or exceeding industry standards.

Fiber Reinforced Polymer (FRP) Systems are simply defined as high-strength and lightweight reinforcements created by combining carbon or glass fibers bonded with adhesive resins. The utilization of FRP strengthening systems have become increasingly popular in construction and retrofit applications, specifically in aging, damaged or overloaded concrete structures.

The primary benefit of CSS products versus traditional retrofit methods is that significant flexural, axial or shear strength gains can be realized with an easy-to-apply composite that does not add significant weight or mass to the structure.

Typical steel plate bonding, concrete section enlargement and steel jacketing have been the strengthening methods of choice for decades, yet corrosion, bond degradation and installation difficulty are consistent challenges to overcome, and the resultant retrofit generally adds weight, reduces usable space, clearance, or both.

There are three common scenarios where FRP has proven to be more economical than traditional strengthening methods:

  • Increases to a structure’s load capacity beyond the original specification or expectation
  • Seismic strengthening
  • Repairs to concrete structures that become damaged over time
Features & Benefits

In many cases, FRP is the most economical choice given the reduced preparation and labour costs. FRP systems can usually be installed without taking the structure out of service.

  • Economically increase capacity without significant weight or mass
  • Extremely high tensile strength
  • Lightweight and user-friendly installation
  • Non-corrosive
  • Low aesthetic impact
  • Compatible with many finishes and protective coatings
Applications

Our line of CSS products provides structural strengthening solutions for:

  • Seismic Retrofit: Shear Strengthening, Displacement/Ductility, Life Safety
  • Damage Repair: Concrete structures that become damaged over time, Deterioration/Corrosion, Blast/Vehicle Impact
