Dead load bending moment dead weight of slab = 12kn/m², dead weight of w.c = 1.76kn/m², total load = 14n/mm²,
Dead load bending moment (m_g) = (14×10.42)/8 = 190knm.

Cable strayed bridges are preferred to convential suspension bridges for long spans mainly due to reduction in bending moment in stiffening girder resulting in smaller section of girders leading to considerable economy in overall costs highway bridges can be built of prestressed concrete with spans up 700m and rail bridges up to span range of 400m.

Construction of any structure forms only a small part of whole gamut of construction management and modern approach in construction management involves several diverse functions like designers, estimators, constructors, supervisors, accountants, financial managers, corporate secretaries, tax planners working under professional managers.

The rigidity of joint does not significantly affect forces developed in members and hence analysis is generally carried out on assumption of hinged joints and action of rigidity joint is flexible and tough enough towards deflection.

The bottom tie members should be of sufficient size to house pretensioned wires or post tensioned cables and depth is around 200mm for spans of 15m and increasing to 300mm for spans of 30m.

The configuration of truss depends upon shape of roof and its general layout and in Russia trusses are generally adopted for industrial buildings having spans greater than 18m and a central I girders and deck is suspended by cable stays comprising parallel wire cables of BBR-HIAM type with ir own anchorage system.

d? = 40mm, D = 200mm
d?/D ratio = (40/200) = 0.2mm.

The design of joint should allow free translation, deflection and rotation of structure at edges without damage or in convenience to traffic and expansion joint should be strong enough to withstand knocking of wheels of vehicles passing over bridge deck.

The second Hooghly bridge (vidyasagar sethu) at Kolkata is an excellent example of: Cable strayed bridge comprising a main span of 457.2m and two side spans of 182.8m each and deck is made of concrete slab 230mm thick two outer steel I girders 28.10m apart.

The cracking load = (50000 (0.8 x 9.43) + 4.0 / 1000),
Section adapted = 50000, ? = 0.8, f_ct = 9.43, A_s = 4.0 (A_s is minimum reinforcement of 0.8 percent in section).
