The True Mean Square Value of Response for a Single Degree of Freedom System by Robin C. Ferebee and Jess H. Jones
نویسندگان
چکیده
During ascent of a space vehicle system from its launching pad, the noise generated by its propulsion system creates considerable vibratory motion in the vehicle structure. Consequently, any component and/or payload attached to the structure will experience a dynamic loading condition. Predicting these acoustically induced "random" loads is difficult because of the complexity of the acoustic environment and the vehicle structure. Conventional finite element analysis can be used to predict the response, i.e., loads, for relatively low frequency vibration, but the number of degrees of freedom becomes prohibitive for higher frequencies.

In this paper a simple tool for seismic design of steel structures for a selected ductility level is presented. For this purpose, a consistent set of earthquakes is selected and sorted based on the maximum acceleration of ground surface. The selected records are applied as the base motion to a single-degree-of-freedom system with strain hardening and the maximum response acceleration is determi...
