Megajaya Sein. Bhd. is a consulting company specialized in analyzing and designing bridges inAlar Setar, Kedah. This company has been assigned to analyze and propose a bridge trussdesign to cross Sungai Kechi! in Yan, Kedah for Malayan Railways Limited. Figure 3 showsthe cross-section of the Sungai Kechil. The required clear span for the proposed bridge truss is6 m length from A to B. The bridge truss was subjected to a maximum load of 132 kN/m alongthe bridge truss span and a maximum length of the truss member is not more than 2.5 m. (a) Sketch a bridge truss that is internally and externally stable and the maximum lengthof the truss, the member is not more than 2.5 m? (b) Calculate the support reactions at A and B by assuming pinned support at A and rollersupport at B. (c) Determine the compression and tension force for each bridge truss member usingMethod of Joint.( d) Check any THREE (3) bridge truss member using Method of Section for validationpurpose.
SCENARIOThe Client who is a private investor needs a 5 storey, framed college building. The building frameprovides the structure for a series of high specification lecture rooms, exhibition hall and meetingrooms which are intended to be built in the south of England, around Heathrow Airport. The collegeblock can be developed with steel or concrete or a combination of both. The college block has a plandimension of 50m by 24 m. The span of the beams and columns can be chosen based onRC or steel frame. Outside the college building, there is a space to be used for exhibitions whichneeds to be covered with a tensile structure. Provide two different design solutions for the exhibition space roof in the given scenario and comparethose solutions to the given scenario.

Please answer question 2, thanks. 1.For the loading and material information shown below, according to EC3, design and check the bending and shear capacities of steel beam which is 10 m long for carrying the listed loading. Information: Beam span length = 10 m, Bay width = 6 m, Slab depth = 20 cm, Partitions = 0.75 kN/m2 , Imposed load = 2.5 kN/m2 , Concrete density = 24 kN/m3 , Steel grade = S355 . Design the beam as a restrained beam as lateral restraint is provided by the concrete slab. Simple support condition of beam ends can be assumed. Check also the deflection of the beam and see if it can satisfy the serviceability limit states or not. 2. For the beam in Question 1, check the corresponding reduced moment capacity for high shear case assuming that VEd / Vpl, Rd = 0.7 .
