以鋼桁梁橋為代表的桁架結(jié)構(gòu)在各類工程設(shè)計中越來越多的被采用，連續(xù)鋼桁梁橋以其跨越能力強(qiáng)、自重小、制造方便、安裝速度快、施工工期短等優(yōu)點(diǎn)成為建造大跨度橋梁時的首選方案。本設(shè)計為設(shè)計計算跨度為3*120m的下承式變截面雙線鐵路連續(xù)鋼桁梁橋。 本設(shè)計主要進(jìn)行上部結(jié)構(gòu)和制動墩的設(shè)計。首先進(jìn)行上部結(jié)構(gòu)設(shè)計，主桁節(jié)間長度定為12m，桁間距為11.2m，邊支點(diǎn)桁高14m，中支點(diǎn)桁高25m。主桁桿件選擇箱形截面、橫向連接采用工字形截面，擬定截面尺寸。然后利用有限元法建立橋梁結(jié)構(gòu)模型并模擬橋梁結(jié)構(gòu)可能受到的各種荷載，根據(jù)橋梁桁架在恒載加活載組合作用下的變形來設(shè)置預(yù)拱度。然后根據(jù)結(jié)構(gòu)在最不利荷載組合作用下的內(nèi)力值，對桿件進(jìn)行受力檢算并設(shè)計節(jié)點(diǎn)板和進(jìn)行節(jié)點(diǎn)板的檢算。最后進(jìn)行橋墩的設(shè)計，選用重力式橋墩，設(shè)計制動墩的形式及截面尺寸，把桁架在支座處的反Sample TextSample TextSample Text力值和橋墩所受的各種附加力進(jìn)行荷載組合，取最不利組合對制動墩進(jìn)行檢算�！� |

| Truss structure with steel truss bridge represented in various engineering design is more and more widely adopted, continuous steel truss bridge with its strong spanning ability, light weight, convenient manufacture, installation speed, short construction period and other advantages become the preferred solution to build large span bridge at. The design for the design and calculation of span of 3*120m under variable section of double-track railway continuous steel truss bridge.Design the design of the main structure and the braking pier. Firstly, the upper structure design, the main truss internode length is 12M, girder spacing of 11.2m, and high 14m in the fulcrum fulcrum truss, truss 25m. The main truss member selection box section, transverse connection adopts I-shaped cross-section, developed section size. And then establish the bridge structure model and various load simulation of bridge structure by using the finite element method, according to the deformation of bridge truss under constant load and live load under combined to set pre-camber. Then according to the internal forces of the structure under the most unfavorable combination of loads, stress calculation and design of gusset plate and gusset plate calculation of rod. Finally the bridge design, selection of gravity pier, form and the section size of the braking pier, the additional stress on the bearing truss by the Sample TextSample TextSample Text force value and the pier load combinations, the most unfavorable combination calculation of braking pier |

A steel truss bridge truss structure represented by the various types of engineering design is increasingly being adopted for its continuous steel truss bridge crossing ability, small weight, ease of manufacture, installation speed, short construction period, etc. become construction of large-span bridges the preferred solution. The design for the design calculations span of 3 * 120m of variable cross section under the deck wire Railway Continuous Steel Truss Bridge. The design is mainly for the upper structure and braking pier design. First, for the upper structure design, the length of the main truss section as 12m, truss spacing of 11.2m, side stringers pivot high 14m, high beam fulcrum 25m. Main truss rod selection box sections, connected by transverse-shaped cross-section, intended sectional dimensions. Then using the finite element method to build a bridge structure model and simulate the bridge structure may be subject to various loads, according to the bridge truss dead load plus live in deformation under load combinations to set camber. Then according to the structure in the most unfavorable load combination internal forces under the action of the force rod for inspecting calculation and design for gusset plate and gusset plate check calculation. Finally pier design, selection of gravity piers, pier design in the form of brake and cross-sectional dimension, the truss at the supports anti-Sample TextSample TextSample Text force value and the pier suffered various additional force load combinations, taking the most unfavorable combination pier for the brake check calculation. |
