The existing practice in Bangladesh for erection of girders is setting the girder immediately at the Temporary Bearing pad and joining the adjacent spans in deck slab degree with the aid of adopting enlargement joints, because the bridges are presently designed as actually-supported beam bridge. the primary drawback of this sort of bridges is that, the seismic resistance Is susceptible, and beneath the outside force past the design variety, the bridges are much more likely to fall in Temporary Bearing chance due to failure in girders. also they have got expansion joints for every span, which affects the comfort of driving and the general integrity of the bridge deck is bad [1]. therefore, layout and construction of the bridges have been revised to establish continuity between girders of two adjoining spans and transform the bridge as clearly supported non-stop beam bridge [2]. transient bearing (sandbox) method is proposed on this paper to solve the machine transformation of continuous beam bridges. design of the temporary bearing is very simple and may be synthetic at web site. This method has been proved in construction of Arial Kha Bridge and may be carried out for other comparable bridges in Bangladesh.
production of non-stop girder bridge is done with the aid of launching the girders as sincerely supported span and the girders of adjoining spans are made continuous by using casting the girder cease joint phase on pier top. To solid the give up joint at website online, the girders of adjoining two spans Temporary Bearing want to be positioned at their preferred position towards the permanent bearing pad with the assist of brief support. After gaining the target electricity at the “forged-in-situ” girder joint section, and after final touch of stressing and grouting for negative moment tendons, transient bearing is launched and the girder is placed on the permanent bearing pad [3] . The overall performance of brief bearings on this approach is crucial. temporary bearings ought to have enough energy, stress, balance and ease of disassembly. when the brief bearing is removed, the beam body can be uniformly and stably positioned at the constant bearing pad. the use of this method, creation of the bridge could be very easy and rapid as compared to the present practice which has been proved in creation of Arial Kha Bridge.
