Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The wind excitation induces fluctuating stresses with randomly varying amplitudes around mean deformation states leading to fatigue damage accumulation. For the design of such structures, it is important to study their dynamic behavior and fatigue damage under wind excitation. In the present work structure has been modeled with two node space truss element. Equivalent static wind loads has been calculated as per IS 875-1987(part3). The corresponding joint deflections, forces in each member and, base reactions has been computed. The eigen value analysis was performed to get natural frequencies and mode shapes of the tower. The natural frequencies up to ten modes have given, and the first four mode shapes were plotted. The wind velocity is considered as stationary zero mean random process superimposed over mean velocity. The mean velocity profile has been described by a logarithmic law, while Kaimal power spectral density (PSD) function of the wind fluctuation has been used to describe the random component. The cross-spectral density of wind fluctuation at different elevations has been found by using coherence, function. 128 pp. Englisch.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Culverts are required to be provided under earth embankment for crossing of water course like streams, Nallas across the embankment as road embankment cannot be allowed to obstruct the natural water way. The culverts are also required to balance the flood water on both sides of earth embankment to reduce flood level on one side of road thereby decreasing the water head consequently reducing the flood menace. Culverts can be of different shapes such as arch, slab and box. These can be constructed with different material such as masonry (brick, stone etc) or reinforced cement concrete.Since culvert passes through the earthen embankment, these are subjected to same traffic loads as the road carries and therefore, required to be designed for such loads. The scope of this has been further restricted to the structural design of box. The structural design involves consideration of load cases (box empty, full, surcharge loads etc.) and factors like live load, effective width, braking force, dispersal of load through fill, impact factor, co-efficient of earth pressure etc. The structural elements are required to be designed to withstand maximum bending moment and shear force. …

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Des ponceaux doivent être prévus sous les remblais de terre pour traverser les cours d'eau comme les ruisseaux, Nallas à travers le remblai car les remblais de la route ne peuvent pas obstruer le chemin naturel de l'eau. Les ponceaux doivent également équilibrer les eaux de crue des deux côtés du remblai de terre pour réduire le niveau d'inondation d'un côté de la route, diminuant ainsi la hauteur d'eau et réduisant la menace d'inondation. Les ponceaux peuvent être de différentes formes telles que l'arche, la dalle et la boîte. Ils peuvent être construits avec différents matériaux tels que la maçonnerie (brique, pierre, etc.) ou le béton de ciment armé. Comme les ponceaux traversent le remblai de terre, ils sont soumis aux mêmes charges de circulation que la route et doivent donc être conçus pour ces charges. Le champ d'application de cette disposition a été restreint à la conception structurelle des caissons. La conception structurelle implique la prise en compte des cas de charge (boîte vide, pleine, charges supplémentaires, etc.) et de facteurs tels que la charge utile, la largeur effective, la force de freinage, la dispersion de la charge à travers le remblai, le facteur d'impact, le coefficient de pression de la terre, etc. Les éléments structurels doivent être conçus pour résister à un moment de flexion et à une force de cisaillement maximum.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Voor het oversteken van waterlopen zoals beekjes is het noodzakelijk dat er duikers onder de aarden wal aanwezig zijn, Nallas over de wal als wegdek mag de natuurlijke waterweg niet belemmeren. De duikers zijn ook nodig om het overstromingswater aan beide zijden van de aarden wal in balans te brengen om het overstromingsniveau aan één kant van de weg te verminderen, waardoor de wateropzet wordt verminderd en de overstromingsdreiging dus wordt verminderd. De duikers kunnen verschillende vormen hebben, zoals een boog, een plaat of een doos. Deze kunnen worden gebouwd met verschillende materialen zoals metselwerk (baksteen, steen, enz.) of gewapend cementbeton. Aangezien de duiker door de aarden wal loopt, worden deze aan dezelfde verkeersbelastingen onderworpen als de weg en moeten ze dus voor dergelijke belastingen worden ontworpen. De reikwijdte hiervan is verder beperkt tot het constructief ontwerp van de kist. Bij het constructieve ontwerp wordt rekening gehouden met belastinggevallen (doos leeg, vol, toeslagbelastingen etc.) en factoren als onder spanning staande belasting, effectieve breedte, remkracht, spreiding van de belasting door vulling, impactfactor, co-efficiëntie van de gronddruk etc. De constructiedelen moeten zo worden ontworpen dat ze bestand zijn tegen het maximale buigmoment en de maximale afschuifkracht.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - É necessário que sejam providenciados cultivos debaixo do aterro para atravessar o curso de água como riachos, o Nallas através do aterro como aterro rodoviário não pode ser permitido obstruir o caminho natural da água. Os bueiros também são necessários para equilibrar a água da inundação em ambos os lados do aterro de terra para reduzir o nível da inundação num dos lados da estrada, diminuindo assim a cabeça de água e, consequentemente, reduzindo a ameaça de inundação. Os bueiros podem ser de diferentes formas, tais como arco, laje e caixa. Estes podem ser construídos com diferentes materiais como alvenaria (tijolo, pedra, etc.) ou betão armado de cimento. Uma vez que o aterro passa pelo aterro de terra, estes estão sujeitos às mesmas cargas de tráfego que a estrada transporta e, portanto, são necessários para serem concebidos para essas cargas. O escopo disto foi ainda mais restrito ao desenho estrutural da caixa. A concepção estrutural envolve a consideração de caixas de carga (caixa vazia, cheia, cargas adicionais, etc.) e factores como carga viva, largura efectiva, força de travagem, dispersão de carga através de enchimento, factor de impacto, coeficiente de pressão de terra, etc. Os elementos estruturais devem ser projetados para suportar o máximo momento de flexão e força de cisalhamento.…
