- Description
- The modal-pushover-based-scaling (MPS) procedure, currently restricted to symmetric-plan buildings, is extended herein to unsymmetric-plan buildings. The accuracy of the extended MPS procedure was evaluated for a large set of three-degree-of-freedom unsymmetric-plan structures with variable stiffness and strength. The structures were subjected to nonlinear response history analysis considering sets of seven records scaled according to the MPS procedure. Structural responses were compared against the benchmark values, defined as the median values of the engineering demand parameters (EDPs) due to 30 unscaled records. This evaluation of the MPS procedure has led to the following conclusions: (1) The MPS procedure provided a highly accurate
estimate of the median EDPs and reduced the record-to-record variability of the responses. (2) The MPS procedure is found to be much superior compared to the ASCE/SEI 7-05 scaling procedure for three-dimensional analysis.

- Description
- Although an importance factor of 1.5 may promote adequate performance of essential facilities built in firm soil;
the actual value of this factor corresponding to structures built in soft soil exhibits significant dependence with
respect to the dynamic characteristics of the structural system. Because of this, the current use given to the
importance factor may result in conservative or unsafe design of essential facilities built in soft soils. One way to
improve the seismic design of essential facilities is to formulate displacement-based approaches. Within this
context, a displacement-based methodology should aim at controlling simultaneously the level of structural and
non-structural damage by limiting the plastic rotation and inter-story drift demands in the structural system of the
essential facility.
