at these facilities after an event. This blast-resistant design objective is called a shelter-in-place performance level, which provides protection for facility staff and assures structural... and the lateral load resisting system of the building (roof diaphragm, moment resisting frame, shear walls). These components may lack the capacity to provide the required level... options that will resist the design blast load with an acceptable level of performance. This work can include cost estimates for each concept that is approved by the client...

We are investigating the injuries to eyes and skin from shards and delaminated glass generated by ballistic impact. We continue to develop fast...

dynamic response resistance functions for use in single-degree-of-freedom (SDOF) analyses based on the material properties and lab test results provided by PPG. In support... blast and impact threats. At the same time as we were performing these tests we also developed the preliminary connection designs for panel-to-panel gravity and lateral connections... a more robust material model and resistance function that includes flexure, shear and localized response (localized damage) for use in SDOF analysis by designers for specification...

We partner with several organizations to conduct these programs... be selected and either uniformly distributed or concentrated loadings can be modeled. A flexure resistance function is used with compression membrane and/or tension membrane contributions... where applicable. P-delta effects on components subject to axial load can also be modeled.
