Maximum Incremental Velocity

Post by huffte » 16 Apr 2013, 22:49

Some research (see #1 below) suggests a correlation between inelastic displacement amplification and maximum incremental velocity (MIV). In fact, one researcher has gone so far as to develop a ground motion prediction model for MIV (see #2 below). MIV is defined as the maximum area under the acceleration time history between two successive zero-crossings.

It might prove useful for researchers to have MIV added to the ground motion parameters calculated by SeismoSpect. This will facilitate future correlation work between inelastic amplification factors and MIV.

Thanks very much as always.

Many thanks for this interesting suggestion, which we will be keeping in mind when preparing future releases of the software.

Thanks again,
