(116 m) and the tipping operation was performed over the water, leaving very little room to maneuver. The schienenzeppelin (ie the rail zeppelin) was a prototype propellor-driven light-weight railcar that held the world railway speed record for no less than twenty years. The first impregnation ratios of the HM, MM and HS carbon tows, which were defined as (the weight of epoxy resins/the weight of the HCFRP sensor) × 100%, were 49%, 51% and 52%, respectively. This type of girder is usually used in high-speed railway bridge construction projects. 2 -7 A 12” wide by 20” deep concrete beam is reinforced with three No. Specified compressive strength of concrete at time of initial loading or prestressing, f' ci = 4000 psi (28 MPa) Specified compressive strength of concrete after 28 days, f' c = 4500 psi (31 MPa). The weight of each span was approximately 2300 tons, which represents the longest and heaviest documented precast prestressed girder spans moved into place using SPMT’s in the United States. The main girders carry runways for a winch-trolley or portal crane that bridges the girders and runs the entire length of the gantry to pick up precast segments from the ground or the leading end of the completed bridge. In the present study the tendons arrangement is not assumed as fixed rather it is considered as de-sign variable as it has significant effects on prestress losses and flexural stress at various sections along the girder. Enter the whole weight lasting on the girder, NOT the wieght per meter etc. Formula for the Weight of Girders. be able to support the weight of an entire span, they are among the heaviest erection equipment used for bridge construction. Besides, it has a light self weight and cost lower. The shortest girder in Span 2, C,5, has a corresponding reaction of only 50 kips (222 kN) This pattern is in agreement with the intuitive notion that reactions should increase with increasing girder lengths. These are then incorporated within the in-situ topping. 150 x 1 x 2400 = 360 kg which is equivalent to 3. Girder is hanged up by chain pulley as shown in sketch and rotation of the hanged girder is controlled manually with the help of ropes.

This included the self-weight of the steel girder, an additional 10% allowan ce for steel detailing elements (e. The self weight of the girder is computed from the section properties and the unit weight with reinforcement. Building self weight itself contributes around 65-70% of the total loads, yes it is a big number. The girder design can be modified in subsequent rating runs to correct overstress or understress, however the most efficient design is achieved when a thoughtful effort is made to arrive at a noncomposite dead load estimate which anticipates the self weight of the generated design. The camber of the model girder due to prestress is shown in Figure 7. 6 2x6 2x4 2x4 4. The self‐weight of the girder is a key driver in major bridge designs since it must be carried by all other bridge components, such as cables, towers, anchorages and foundations. (3) THE SEAT WIDTH MAY VARY BASED ON DESIGN. Bottom Panel — Used as a brace for bridge girders. By contrast,. Moreover, self-weight of the structural steel of the girder components was applied on the model at this stage. Box girder. The dead load carried by the girder or the member consists of its own weight and the portions of the weight of the superstructure and any fixed loads supported by the member. Self-weight of cover beam: 650kN; self-weight of bottom form: 12. the small weight of the structure earthquake load has been left out. • Steel girder self weight (DC1) • Concrete deck self weight (DC1) • Haunch self weight (DC1) • Barrier walls (DC2) DW dead loads (structural attachments) include: • Wearing surface (DW) 2. The PSC girder having high clearance has several disadvantages in that moment applied to the girder is increased due to increased self-weight as the PSC girder uses a great deal of concrete, in that aseismatic design of piers is not economical, and in that a bridge spanned above a road is deteriorated in economic efficiency since lots of banks. University of Architecture, Civil Engineering and Geodesy. 3) weight of slab per sq. Let, Assume the slab has a thickness of 125 mm. Honeycomb girder features light self-weight, high stiffness, low deflection and high wind resistance.
