Iran Nezam Civil Design Exam study guide
Iran Nezam Civil Design Exam · Work through your exam, one topic at a time.
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 study guide has 10 sections and about 2,633 words.
01Structural Analysis and Design
Candidates must be fluent in statics (equilibrium, determinacy, influence lines), classical methods (virtual work, moment distribution, slope-deflection), and matrix stiffness analysis. Understand how support conditions change a structure from determinate to indeterminate, and how to compute reactions, shear and moment diagrams, and deflections.
300 words, about 2 min02Reinforced Concrete Design
Master flexural design (singly and doubly reinforced sections), the equivalent rectangular stress block, tension- and compression-controlled behavior, and the strain limits that separate them. Understand shear design (concrete contribution plus stirrups), development length and anchorage, and serviceability checks (deflection, crack control).
307 words, about 2 min03Steel Design
Understand tension member design (gross yielding, net section fracture, block shear), compression members (Euler buckling, effective length factor K, slenderness limits), and flexural members (yielding, lateral-torsional buckling, local buckling of flanges and webs). Know bolt and weld design: shear, bearing, tear-out, and combined actions.
283 words, about 1 min04Geotechnical Engineering and Foundations
Know soil classification (grain size, Atterberg limits, USCS), effective stress (total stress minus pore pressure), consolidation settlement, shear strength (Mohr-Coulomb, c and φ), and bearing capacity (Terzaghi and general forms). Understand shallow foundations (spread footings, bearing pressure distribution), deep foundations (pile capacity from skin friction and end bearing), and lateral earth pressure (Rankine and Coulomb).
276 words, about 1 min05Seismic Design and Earthquake Engineering
Understand seismic hazard (ground motion, site effects, response spectra), structural dynamics (period, damping, mode shapes), and ductile design philosophy (capacity design, strong column–weak beam). Know base shear calculation, load distribution over height, drift limits, and detailing requirements for ductile behavior.
258 words, about 1 min06Concrete Technology and Materials
Know cement chemistry and hydration, water-cement ratio and its effect on strength and durability, aggregate properties (gradation, shape, absorption), admixtures (air-entraining, plasticizers, retarders, accelerators), and mix design. Understand workability tests (slump, slump flow), curing, and the factors affecting compressive strength and durability (permeability, freeze-thaw, sulfate attack).
241 words, about 1 min07Construction Management and Project Planning
Understand project delivery methods (design-bid-build, design-build, CM-at-risk), the critical path method (CPM), float (total and free), resource leveling, earned value management (PV, EV, AC, CPI, SPI), and cost and schedule control. Know contract types (lump sum, unit price, cost-plus) and their risk allocation.
271 words, about 1 min08Building Codes, Regulations, and Statutory Requirements
Know the hierarchy of codes (national building code, seismic provisions, material codes), occupancy classifications, allowable height and area limits, egress requirements (travel distance, exit width, dead-end corridors), fire-resistance ratings, and accessibility requirements. Understand the permit and inspection process and the roles of the authority having jurisdiction (AHJ).
244 words, about 1 min09Surveying, Mapping, and Site Layout
Understand leveling (differential, trigonometric), distance measurement, angle measurement (theodolite/total station), traverse computations (bearings, latitudes and departures, closure), coordinate systems, and setting out (horizontal and vertical control). Know contour maps, slope, and earthwork volume (average end area, prismoidal).
232 words, about 1 min10Hydraulics, Water Supply, and Sanitary Systems
Understand fluid properties, continuity, Bernoulli and energy equations, friction losses (Darcy-Weisbach, Hazen-Williams), minor losses, and open-channel flow (Manning's equation). Know water supply design (demand, pressure, storage), pipe sizing, and sanitary drainage (fixture units, slope, venting).
