STR.C2 - Concrete Shear Walls
The following models are available:
STR.C2.HC | Structural, Concrete Shear Walls, Low-Rise, High-Code
Structural components represent the structural system in the building.
Structural System: The vertical components of the lateral force-resisting system in these buildings are concrete shear walls that are usually bearing walls. In older buildings, the walls often are quite extensive, and the wall stresses are low, but reinforcing is light. In newer buildings, the shear walls often are limited in extent, generating concerns about boundary members and overturning forces.
Low-Rise Building with 1-3 stories.
Design Level Approximate Basis:
Post-1975 construction in UBC Seismic Zone 4, NEHRP Map Area 7.
Suggested Block Size: 1 EA (round up to integer quantity)
STR.C2.LC | Structural, Concrete Shear Walls, Low-Rise, Low-Code
Structural components represent the structural system in the building.
Structural System: The vertical components of the lateral force-resisting system in these buildings are concrete shear walls that are usually bearing walls. In older buildings, the walls often are quite extensive, and the wall stresses are low, but reinforcing is light. In newer buildings, the shear walls often are limited in extent, generating concerns about boundary members and overturning forces.
Low-Rise Building with 1-3 stories.
Design Level Approximate Basis:
1941-1975 construction in UBC Seismic Zone 2B, NEHRP Map Area 5
Post-1941 construction in UBC Seismic Zone 2A, NEHRP Map Area 4
Post-1975 construction in UBC Seismic Zone 1, NEHRP Map Area 2/3
Suggested Block Size: 1 EA (round up to integer quantity)
STR.C2.MC | Structural, Concrete Shear Walls, Low-Rise, Moderate-Code
Structural components represent the structural system in the building.
Structural System: The vertical components of the lateral force-resisting system in these buildings are concrete shear walls that are usually bearing walls. In older buildings, the walls often are quite extensive, and the wall stresses are low, but reinforcing is light. In newer buildings, the shear walls often are limited in extent, generating concerns about boundary members and overturning forces.
Low-Rise Building with 1-3 stories.
Design Level Approximate Basis:
Post-1941 construction in UBC Seismic Zone 3, NEHRP Map Area 6
Post-1975 construction in UBC Seismic Zone 2B, NEHRP Map Area 5.
Suggested Block Size: 1 EA (round up to integer quantity)
STR.C2.PC | Structural, Concrete Shear Walls, Low-Rise, Pre-Code
Structural components represent the structural system in the building.
Structural System: The vertical components of the lateral force-resisting system in these buildings are concrete shear walls that are usually bearing walls. In older buildings, the walls often are quite extensive, and the wall stresses are low, but reinforcing is light. In newer buildings, the shear walls often are limited in extent, generating concerns about boundary members and overturning forces.
Low-Rise Building with 1-3 stories.
Design Level: Approximate Basis: UBC Seismic Zone 0, NEHRP Map Area 1.
Pre-1941 construction in all other UBC and NEHRP areas.
Pre-Code damage functions are appropriate for modeling older buildings that were not designed for earthquake load, regardless of where they are located in the United States.
Suggested Block Size: 1 EA (round up to integer quantity)
