Abstract: A combined plate-beam unit analysis method considering a residual stress effect of an orthotropic plate, which is used for analyzing an orthotropic steel bridge deck welded by a top plate of a bridge deck and a trapezoidal rib, the top plate of the bridge deck is analyzed by a flat shell unit, while each sub-plate forming a trapezoidal rib is analyzed by a plate-beam unit.

The combined plate-beam unit analysis method has the advantages of less freedom and high calculation accuracy, so it is especially suitable for structural analysis of the trapezoidal rib orthotropic plates.

The techniques include determining that a scheduled snapshot of a storage volume is imminent, where the storage volume stores input/output (I/O) data associated with an application that executes on a host server. The techniques further include initiating at least one host buffer flush prior to the scheduled snapshot being performed, where I/O data in a host buffer associated with the application is transferred to a write cache of the storage volume to reduce an amount of I/O data in the host buffer when performance of the scheduled snapshot begins. The techniques further include initiating, after the host buffer flush has completed, a write cache flush to write the I/O data in the write cache to the storage volume. The techniques further include initiating the scheduled snapshot of the storage volume in response to an indication that the write cache flush has completed.
