Introduction to theStructural Engineer (SE)License ExamSEDr. Soliman Khudeira, SE, PESoliman.Khudeira@iit.eduSK1
Importance of Licensing License distinguishes you among othercandidates / peers Owning a firm (consulting) Only a Licensed Engineer can sign/seal designs Prestigious Shows commitment to the engineering profession You will earn more than peers with a SE U.S. News & World Report: “[Engineering]licensure is crucial for career advancement andtop pay.”SK2
Importance of LicensingYour degree, work references, andtechnical skills are not necessarily anobjective way to assess the engineer’scompetence. However, the SE License isa universal standard that is recognizedthroughout the professionSK3
Steps to be a LicensedStructural Engineer (SE)1. Pass the FE exam, then you are an EIT (or EI)2. Graduate from EAC/ABET-accredited college3. Have 4 years of structural engineering experience(must be under the supervision of a licensed SE)4. Pass the SE I (8 hours exam)5. Pass the SE II (8 ours exam)Then you are a Licensed Structural Engineer (SE)SK4

FE Exam- Computer Based Testing (CBT)Seven free-standing, discipline-specific exams:1. Chemical2. Civil3. Electrical and computer4. Environmental5. Industrial6. Mechanical, and7. Other disciplinesEach exam covers materials commonly found in thatdiscipline's curriculumSK6

The Concept of “Most Nearly” Many problems in the exam ask for the option thatis “most nearly correct.” An answer that exactly matches your calculationsis not always given. The phrase “most nearly” is used to accommodatesolutions that have been derived correctly but thatmay be slightly different from the option given on theexam. Use good engineering judgment when selectingyour option.SK8
The Concept of “Most Nearly”Examples:1. If the problem asks you to determine the load on abeam, then select the option that is most nearly whatyou calculated, regardless of whether it is more orless than your calculated value.2. If the problem asks you to find the size of a beam tocarry a specified load, then select the option that willsafely carry the load. In this case, select the optionthat is equal to or larger than the beam size youcalculated. In other words, do not select a beamsize that is smaller than the size you calculatedSK9

Therefore, thedimensions of the selected beamhas to be more than or equal to 9in. x 3.3 in. The only answer thatsatisfy this condition is “B”hAnswer is B, not DSKBEAM CROSSSECTION12

Allowed Reference Materials in the Exam The SE exam is open book. Candidates maybring printed reference materials, as long as theyare bound and remain bound during the exam. Loose paper may be bound with ring binders,plastic snap binders, spiral-bound notebooks,and screw posts, but not with staples. Sticky notes and flags are permitted only whenthey remain attached to book pages.SK15

SE Exam 16-hours (in addition to passing the FE) The exam uses separate vertical and lateral components: Friday Component – 8 hour Vertical Forces:gravity loads and lateral earth pressures Saturday Component – 8 hour Lateral Forces:Wind/Earthquake Breadth modules are in the morning sessions: containquestions from all structural engineering topics. Allquestions are multiple-choice Depth modules are in the afternoon sessions: you willchoose either buildings or bridges. You must work thesame topic area on both components. All questions areconstructed response (essay)SK18
SE Exam You are not required to obtain acceptableresults on both 8-hour components in a singleexam administration. You can sit for andobtain acceptable results on one component,and then sit for and obtain acceptable resultson the second component at a later date. You must obtain acceptable results on both8 hour components within five year period inorder to pass the SE exam.SK19

Exam Tips Take a mock exam The day before the actual exam: Solve one complete sample exam 20% of each exam consists of questions repeated from previousexaminations - equating subtest Concentrate on subjects that you know well Subjects that you do not know well: be prepared to solve at leastthe easy questions Take-off a minimum of one week before the exam to study andreview In the exam: use a stop watch to monitor the time Tag (w/ tabs) the books If you have to guess, use engineering judgment, not All A’s or allC’s, for example Do not spend inordinate time on any single question Solve first the easy and most familiar questions to you Strategize: It is better to solve 70% of the questions correctly(with high certainty), rather than solving 100% of the questions(with low certainty)SK30
