Experimental Studies on Two-Side Constraint Steel Plate Shear Wall with Vertical Stiffeners
Journal of Northeastern University, 2014Co-Authors: Mu Zai-geAbstract:Two 1 ∶ 3 two-Side Constraint steel plate shear wall specimens with vertical stiffeners were tested under low cyclic loading to study its seismic performance through the performance indexes of the initial stiffness,hysteretic behavior,load-carrying capacity,destruction mechanism and so on.Tests results showed that as main lateral force resisting members two-Side Constraint steel plate shear wall with vertical stiffeners had a very superior seismic performance.In the elastic phase destroyed expected buckling,mainly for the corner plate tearing and buckling failure,the diagonal direction formed apparent tension band can be observed in the steel plate wall destroyed later.So it is worth popularizing in the area of high seismic intensity.

motor vehicle steering system stop limiter for limiting angle of steering lock for steerable vehicle wheels has an electronic control component to determine reset the angle at maximum
2002Co-Authors: Kai Uwe Stoerk, Stefan KirmseAbstract:A steering system has an electronic control component to influence a wheel's angle of steering lock and to determine and reset a maximum possible angle of steering lock by relying on a suitable Side Constraint. It can also have an electric/hydraulic actuator suitably triggered on an electronic path so as to influence the wheel's angle of steering lock, e.g. steer-by-wire.

Modeling the satellite placement problem as a network flow problem with one Side Constraint
Operations-Research-Spektrum, 1991Co-Authors: Susan B. Spälti, Thomas M. LieblingAbstract:Die Placierung von Telekommunikationssatelliten im geostationären Orbit (GSO) führt auf NP-schwierige Optimierungsprobleme, die z. B. mit Nachbarschafts-Suchverfahren, insbes. Tabuverfahren angegangen werden können. Ein typischer Schritt darin besteht in der Festlegung einer Reihenfolge der Satelliten und anschließender Placierung mit linearer Programmierung. Bei solchen Verfahren ist die effiziente Lösung der großen Anzahl auftretender spezieller linearer Programme ausschlaggebend. Wir beschreiben diese linearen Programme, charakterisieren deren Dualprobleme als Netzwerkflußaufgaben mit einer Nebenbedingung und geben dafür ein effizientes Simplex-Verfahren an. Da diese Aufgaben meist stark degeneriert sind, erweitern wir Cunninghams Begriff einer stark zulässigen Basis auf unseren Fall und geben ein darauf basierendes, Zyklen vermeidendes Lösungsverfahren an. Numerische Experimente belegen unsere Behauptungen zur Effizienz der Verfahren. The placement of telecommunication satellites in the geostationary orbit (GSO) gives rise to NP-hard optimization problems usually approached with iterative neighborhood (possibly tabu) search schemes. A typical iteration thereof consists in fixing an order for the satellites and determining their actual locations by linear programming. In such procedures it is crucial to efficiently solve the very large number of arising special linear programs. We describe those linear programs, characterize their duals as special network flow problems with one Side Constraint and then present an efficient network simplex method to solve them. Since these problems can be highly degenerate, we generalize Cunningham's concept of strongly feasible bases to our case and present a procedure based thereupon which prevents cycling. Computational experience with our algorithms substantiates our efficiency claims.
