Iran Nezam Civil Design Exam case studies
Iran Nezam Civil Design Exam · Put your knowledge to work in context.
The Iran Nezam Civil Design Exam is the professional licensing assessment through which civil engineers in Iran demonstrate the competence required to practise as design engineers. It is intended for graduates holding a civil engineering degree who wish to obtain a professional licence, and it is also relevant to engineers preparing to take responsibility for the design of building structures. The Iran Nezam Civil Design Exam case studies are 5 cases and about 3,422 words.
1Raft Foundation on Partially Saturated Clay After Groundwater Drawdown
A five-storey RC building with a 25 m x 18 m raft (thickness 900 mm) sits on a 12 m thick layer of stiff-to-very-stiff silty clay over dense sand. The design assumed a groundwater table at 1.5 m depth and an allowable bearing pressure of 180 kPa.

A 12-storey RC shear wall in a high-seismicity zone is 300 mm thick, 4.0 m long, and carries a factored axial load of 6,500 kN at the base under the governing seismic combination. Concrete is C30 (fck = 30 MPa), longitudinal boundary reinforcement is 12Ø25 in each boundary element (As ≈ 5,890 mm² per element), and the wall is designed as a ductile (special) shear wall.

A four-storey steel moment frame uses built-up I-sections for the beams (welded plate girder, flange 300×20, web 600×10, S355). The connection is a welded unreinforced flange-bolted web (WUF-B) detail.

A 400 m gravity sanitary sewer runs from a new development to an existing trunk main. The design slope is 0.4% (S = 0.004), pipe is 300 mm concrete, Manning n = 0.013, design peak flow 45 L/s.
655 words, about 3 min5Concrete Cube Failures on a Slab Pour and the Strength-Acceptance Decision
A 250 mm two-way suspended slab was cast from ready-mix C30 concrete (fck = 30 MPa, target mean ~38 MPa). At 28 days, three cubes from the same batch gave 31, 26, and 24 MPa.
