How to Structurally Design a Concrete Slab Culvert? RC Slab Deck Design Using the FORTRAN-95 Program

Master's Thesis from the year 2013 in the subject Engineering - Civil Engineering, grade: Very Good (A), Addis Ababa University (Addis Ababa University Institute of Technology), course: Structural Engineering, language: English, abstract: This thesis focuses on the development of a FORTRAN 95 program for the structural design of the superstructure part of a concrete slab culvert. FORTRAN 95 is a programming language used in the fields of scientific, numerical, and engineering fields. In this thesis, this language has been used to develop the program for the structural design of reinforced concrete slab culvert deck. The input data for at grade and at fill slab culverts are saved on a note pad in the external file folder which constitute the material properties, geometric features and proposed diameter of reinforcement bars of the slab culvert and its deck in the folder which contains FORTRAN 95 program. The output data is written on the note pad in the external folder based on the format assigned for each output in the folder which contains the design results of slab deck thickness and area, spacing and length of main, distribution and temperature reinforcement bars. Besides Edge beam design parallel to the traffic is executed and shown in the output result by the developed program. Concrete slab culvert is an important structure used to convey trucks and pedestrian along a road corridor or in one of a range of other situations. This structure is highly constructed in highway road projects in Ethiopia. In this study, a FORTRAN program is developed for the structural design of reinforced concrete slab culvert deck according to the provisions given in AASHTO LRFD Bridge 2005 Edition.The developed program is expected to assist the structural designers and users to design the superstructure part of a reinforced concrete slab culvert deck efficiently with great accuracy. Both at grade and at fill slab deck thicknesses are computed according to the specification specified in AASHTO LRFD Bridge 2005 Edition. The reinforcement bars are also designed based on the requirements specified in the code. Within the context of this work the program is developed in four steps. The first step is to define and analyze the problem; the second step is to develop an optimal solution and designing the program, the third step is coding the program and the final step is testing and documenting the program.

My name is Andinet Zeleke Bekele and 40 years old married man. I was born in Ambo town, Ethiopia on February 04, 1980. My father was police officer and my mother is house wife. I have five brothers and two sisters. I married in 2013 and currently I have two boys and one daughter. I studied Civil Engineering degree and MSc degree in Structural Engineering at Addis Ababa University in 2004 and 2013 respectively. My MSc degree thesis title was 'Development of Computer Program for the Structural Design of Concrete Slab Culvert Deck'. The program was written on FORTRAN-95 software after the thesis paper was fully completed. I finalized my MSc degree program with GPA of 3.68 and got 'very good' result for the Thesis work. Besides, I took short training and got certificates from International Academy and different national institutions. Certificates received from; • Indian Academy of Highway Engineers in 2015. • International Leadership Institute in 2014 • Ethiopian Roads Authority (ERA) Sponsored training given by HABCON Consult PLC in 2013. For 15 years from 2004 to 2019, I worked in different titles from supervisor to diverse managerial posts at governmental construction sector in Ethiopia. From 2005 to 2014, I worked at highway construction projects as supervisor, office engineer and engineering service team leader. For two years from 2014 to 2016, I worked as road design team leader in Ethiopian Road Construction Corporation. For three years from 2016 to 2019, I worked in different sections of Ethiopia Construction Works Corporation as project management department manager, building construction department manager and Deputy CEO Engineering affairs senior adviser. My professional hobbies are; • Short span Bridge designing (girder and slab bridge types) using Auto CAD and design manuals. • Designing ditches and Pipe, box and slab culvert designing using Auto CAD and design manuals. • Highway road designing using Eagle point software. • Structural designing of low-rise building using ETABS 2009 ..... • Preparation of road templates and pavement road data from the design using Auto CAD and excel spread sheet. • Preparation of working drawings for bridges, culverts, retaining walls from the design using Auto CAD. • Checking and analyzing surveying point data using notepad, excel and Auto CAD, Eagle point. Other hobbies are; • Driving • Listening music Since January 2019, I have started living in Netherlands. Thanks.
