Modeling in SAP2000:

Prestressed tendons are modeled in SAP2000 with the following considerations:

Post-tensioned, bonded tendons

Construction procedure:

Actual behavior:

Modeling in SAP2000:

Post-tensioned, bonded tendons may be modeled with the following considerations:

Post-tensioned, unbonded tendons

Construction procedure:

Actual behavior:

Modeling in SAP2000:

Post-tensioned, unbonded tendons may be modeled with the following considerations:

Post-tensioned, external tendons

Post-tensioned, external tendons are similar to unbonded tendons except that external tendons attach to the concrete at several discrete locations, including anchorage points and deviator blocks.
