This article aims at studying sounding rocket (SR) class, or those vehicles launched from the earth and carrying out various experiments high altitudes. After end of their mission, rockets should deliver a payload to given point give range.
 In general, design tasks are divided into direct inverse ones. paper focuses on designing tasks. this respect, set values maximum range, mass restrict...

Risk assessments performed at the conceptual design phase of a product may offer the greatest opportunity to increase product safety and reliability at the least cost. This is an especially difficult proposition, however, as often the product has not assumed a physical form at this early design stage. This paper introduces the Risk in Early Design (RED) method, a method for performing risk asse...

A parametric formulation for preliminary design of tubed-system tall buildings is presented in which some optimality criteria and practical constraints are considered. Here, a minimum compliance optimization formulation, developed by other researchers, is applied to a framed-tube structure. The tube behavior is modeled as a cantilevered box beam. Independent variable in this problem is thicknes...

1.0 Initial Draft minus cost and implementation plan 16/03/98 gjh 1.1 Added costs and implementation plan. Applied some suggestions from WFRD, TB, PED 29/03/98 gjh 1.2 Added Gantt chart and clarified some points.

The design of tall buildings essentially involves a conceptual design, approximate analysis, preliminary design and optimization, to safely carry gravity and lateral loads. The design criteria are, strength, serviceability, stability and human comfort. The strength is satisfied by limit stresses, while serviceability is satisfied by drift limits in the range of H/500 to H/1000. Stability is sat...
