For the beam below, select stirrup spacings for #3 stirrups if f = 4,000 psi, normal weight concrete and f, = 60,000 psi. P₁ = 30 k @L OL = 3 k/ft WD 2 k/ft (including beam weight) ///////////// 10 ft- -20 ft- -30 ft- 18 in. 24 in.

G-1 The drawing shows the beam (B) and girder (G) layout for the third floor of a commercial building. The live load (LL) for the flow is 45 PSF and the dead load (DL), which consists of a 4" thick concrete slab weighs 50 PSF. For now, we will neglect the weight of the beams/girders. 24 ft 6 ft 6 ft 6 ft 6 ft 6 ft G-2 C6 30 ft G-3 24 ft B-1 B-2 B-3 B-4 B-5 B-6 G-4 Compute the distributed loads applied on girder G-2. Show a FBD of these loads and compute the reactions at columns C2 and C6.

able to help me with the question below with references too for study purpose   Structural InvestigationThe Building Maintenance and Strata Management Act 2004 interprets “Structural elements,for a building means an internal or external load-bearing component of the building or part ofthe building that is essential to the stability of the building but exclude any door or window.”Loading-bearing components such as wall, column or beam, etc, are subjected to externalforces. (a) Interpret the diagnosis of a structural defect and discuss FOUR (4) external forces ona structure element that may cause structural cracks.(b) Discuss the effects of alkali-silica reaction on concrete structures and formulateFOUR (4) preventive measures.(c) Discuss the differences between chloride attack and sulphate attack on concretestructures(d) Formulate preventive measures to prevent or reduce chloride and sulphate attack onconcrete structures   Hard FinishesNatural timber flooring such as timber strips and…
