Small-Scale Tests of MX Vertical Shelter Structures.

摘要

The purpose of this research was to assess the applicability of geometric scaling at very small scale to study the response of buried reinforced concrete vertical shelter structures subjected to airblast loading. The approach was to build and test two 1/30-scale models and compare the responses with those from corresponding 1/6-scale tests. One of the structures tested was designed to respond elastically, and the other was designed to respond inelastically. The 1/30-scale and 1/6-scale models were built with as much geometric and material similitude as practical. Special fabrication techniques were developed for the 1/30-scale models, Concrete sand (ASTM C33) was used for the backfilled soil at both scales. The airblast from a nuclear burst was simulated with a high explosive simulation technique (HEST). (Author)
