Retractable roof structures
j This paper presents a new concept for retractable roof structures. The new structures consist of a foldable lattice of beams connected by cylindrical joints, to which covering panels or membranes are attached. These structures fold towards their perimeter and there is practically no limit to their shape. Solutions to the key problems that have to be solved in the course of the kinematic desig...
متن کاملEvaluation of rainwater harvesting systems performance in runoff production and in grape yields
Low rainfall and its poor distribution in the West Azerbaijan province have hampered agricultural production in dry-land. One of the important solutions in this regard is converting rainfall into runoff. In this study, a field experiment in Khoshalan village of Urmia on grapes in rainfed conditions with supplementary irrigation and rainwater harvesting was carried out in a split-plot design bas...
متن کاملA Multivariate Quality Control Procedure in Multistage Production Systems
In this paper a multivariate quality control procedure is offered in which several correlated stages are present in production systems and in each stage there are several correlated control variable. Using Hotelling's T2 statistic, first, each stage is tested for being out of control. Then out of control variables are selected using Murphy's method. The remainder of the research involves evalua...
متن کاملNew proposal for a retractable roof over a courtyard in Tabriz Islamic Art University
Abstract This paper by reviewing the main examples of small to medium-scale retractable roof structures covering building courtyards is to present an innovative rigid retractable roof system employing spatial frames for a courtyard of an existing building in Tabriz Islamic Art University. The courtyard is currently used for temporary exhibitions and gatherings whenever permitted by environmenta...
متن کاملShape Optimization of Cover Plates for Retractable Roof Structures
Department of Engineering, University of Cambridge Trumpington Street, Cambridge CB2 1PZ, U.K. Abstract The optimal shape of cover plates for circular, symmetric retractable roof structures based on a grid of multi-angulated rods connected by revolute joints is considered. It is assumed that these cover plates are co-planar, and hence they are not allowed to overlap in any configuration; they a...
