Durable, fire resistant, energy absorbing and cost-effective strengthening systems for structural joints and members

A system for reinforcing a structural joint comprising two or more structural members defined by a certain thickness, stiffness, tensile strength, and compressive strength, the system comprising:

• a. a filler module having a stiffness of within 20% of the stiffness of the members, a tensile strength of at least 50% of the tensile strength of the members, damping of 2-20% of critical damping, and a compressive strength of between 160-200% of the compressive strength of the members;
• and
• b. a plurality of dowels for incorporation into the members of the joint and the filler module.

A system for reinforcing a structural joint having two or more structural members defined by a certain thickness, tensile strength, compressive strength, load capacity, energy absorption and stiffness, the system comprising:

• a. a filler module designed and configured to secure to the members of the joint, the filler module having a stiffness within 20% of the stiffness of the members, a tensile strength of at least 50% of the tensile strength of the members, damping of 2-20% of critical damping, and a compressive strength of between 160-200% of the compressive strength of the members;
• and
• b. one or more strips of wrap material of sufficient length to apply about the filler module and the members of the joint, wherein the wrap material comprises fiber reinforced polymer.
