    The residential building shear walls use 7, psi and 10, psi nominally specified concrete strength. And the office building uses 8, psi nominally specified concrete strength. Expected properties equating to 1. Material data was gathered to justify these values. Confinement ties are 80 ksi while shear reinforcing is 60 ksi. Both Grade 60 and Grade 80 are used for longitudinal reinforcing with the configuration depending upon the most economical layout. Grade 80 was chosen to reduce shear wall congestion, improve sustainability, and create savings for the project. Justification for its use are discussed below. Nonlinear Modeling Perform-3D is being used for the nonlinear modeling and response history analysis. Models include the shear wall concrete, reinforcing, lumped gravity columns in proximity to shear walls, and floor framing elements. At rigid diaphragms, single floor framing elements are used on each side of the core.

    Models include the shear wall concrete, reinforcing, lumped gravity columns in proximity to shear walls, and floor framing elements. At rigid diaphragms, single floor framing elements are used on each side of the core. Multiple semi-rigid shell elements, in addition to single floor framing elements, are used at diaphragms near discontinuities or with diaphragms with multiple shear walls.

    Single elements on each side of the core wall are modeled as elastic elements with lumped plastic hinges at the ends representing the rotational capacity of the joint. For the upper half of the residential building, significantly above the top of the podium level where the first wing wall is introduced, rigid diaphragms are modeled.

    Below this, semi-rigid diaphragms are modeled to account for variable diaphragm stiffness. For the office building, the entire building uses semi-rigid diaphragms and shell elements to account for the variable diaphragm stiffness.

    Composite steel beams are lumped together and modeled as one element on each side of each wall element to account for gravity framing outrigger effects. High Strength Reinforcing Background The structural engineering community is always looking for new materials that can improve sustainability as well as provide for more economical buildings.

    High strength reinforcing is no exception.
