Program Outcomes

Precast concrete structures are manufactured off-site in reusable molds. From all the extensive network of tunnels that exists until the present day in Rome makes us suspect that the precast concrete industry began in ancient Rome. However, it was documented as having started in the 1900s. There are several advantages to precast systems:

  • One providing greater freedom for engineers in planning.
  • Basically the casted products arrive at the site completely customized ready for installation. Using precast will actually accelerate the project schedule and is cost saving. 
  • Precast concrete manufacturing is substantially a sustainable process. 
  • They have thermal mass absorption property leading to slow releasing of heat which implies long term energy saving beneficial in cold countries.
  • Additionally, factory production leads to reduction in debris. 

So, sustainable building developers practice precast concrete for LEED certification.

Here is a Master’s course to fulfill the thirst for learning. You will be part of 6 courses that deal with structural analysis and design for G + 15 precast building using ETABS.

ETABS is prevalent in the structural industry across the world. You will be able to get a good refresher of the bending moment and shear force diagrams of various types of structures which is very important to get a job in the field of structural engineering. You will be able to learn approximate methods of analysis of frames and therefore will be quickly able to validate results obtained from hand calculations with what is obtained in ETABS. 

You will come across modern bridge forms such as prestressed I-girders and box girders. The course is based on real-life examples, so you will learn the problems experienced by engineers on a daily basis and where further research might be required to aid the industry. The 6 courses are:

  1. Mastering Bending Moment and Shear Force Diagrams 
  2. Analysis and Design of Buildings using STAAD.Pro - A professional approach
  3. Design of Elevated Metro Viaduct 
  4. Design of RCC and PSC Superstructure
  5. Structural Design of Highrise Precast Buildings 
  6. Reinforced Cement Concrete Design

Advanced topics such as buckling and construction stage analysis will be mentioned, but not covered in depth, as these topics should be subject of the steel bridge superstructure course.

This lecture will focus on the long-terms effects, namely creep, shrinkage and loss of prestress, which had been introduced earlier in the lecture series. They will learn how to calculate long-term section properties. Examples where creep and shrinkage cause parasitic effects will be demonstrated, e.g. moments in continuous prestressed bridges and composite girders.

This part will also discuss the movement ranges and calculations related to the expansion joint specification. Movement and friction at bearings will also be mentioned.

12Construction Stage Analysis

This lecture will demonstrate various ways in which concrete structures can be constructed, e.g. cast-in-situ, launching and balanced cantilever construction. The students will learn that construction sequence can often govern design and that structures should always be checked in their temporary conditions.
