Task

Question 1: Muscat municipality want to design a Unsymmetrical I-section bridge of L m span, which have over all dimensions of top flange (B_ftx T_ft), Over all depth of web D_w and Bottom flange ((B_ftx T_fb), thickness of web (Tw) all dimensions are in mm. The bridge supports a Variable action of M_L KN-m. At the center of the span the prestressing force of P KN is located at e mm from the soffit of the beam. Estimate the stress at the center of the span section of the beam for the following load conditions

a) Self weight + Prestressed; b) Self weight + variable load + Prestress. and discuss which loading condition is suitable for the design of Bridge.

Question 2: Design a car parking for MEC College office of dean and deputy dean by using yield line theory. This is supported as shown in figure below consider the probable yield line pattern and find the yield line moment m Kn-m. This is having dimensions as BxL and total ultimate load of n KN/m². Illustrate the locations of plastic hinge and the ultimate collapse load by using yield line theory.

Parking of slab at AB & AD as fixed support and BC & CD simply supported.

The details of the assessment are as follows:

a) In order to find out whether this I-unsymmetrical beam-girder bridge is stable, students must analyze for respective external load on it with check the permissible limit of stress in tension and compression

b) The purpose of this unsymmetrical I- beam is to check the adequacy girder beam. In order to do so. students must

i. Calculate the structural analyzing calculation and detailing in the form of a drawing

ii. Also consider the respective design stress induced not cross the permissible limit. just for the unsymmetrical I -section"

iii. Form the standard expression first for location of yield lines and collapse load and then solve the plastic moment and problem

Question 3:  In Q. No task II considers a beam AD of Lm spam is to be design for an ultimate uniformly distributed load of M I KN/m and a two point load of WKN as shown in figure below. The beam is simply at B & C and fixed at A. Determine the required plastic moment If the load factor is LF and select a suitable I- section by using steel table. If the Yield stress is σ_y = N/mm²

Question 4: Illustrate the roof of a portal frame ABCD for sloping ground as shown in figure below. Determine the end moments also check the deflection at each span by using stiffness matrix methods. Compared and re-produced the result by using design software.
