Venue: Block 3 Auditorium                               Day 1                                              Date: 22-02-2018

The workshop was inaugurated at 9:00 a.m. with the lighting of lamp by Fr. Antony Puthussery, Campus co-ordinator, Dr. Devraj, Guest Speaker, Prof. Raghunandan Kumar, HOD Department of Civil Engineering, Dr. Arvind H.B, Dr. Narasimha Murthy and CACE student representative. Prof. Raghunandan Kumar welcomed the gathering, followed with the Presidential Address by Fr. Antony Puthussery.

Session 1: Fundamental Concepts of Reliability by Dr. Devraj
Dr. Devraj introduced the participants of the workshop to the topic of reliability. He started with the evolution of codes,the central role of the code is a set of requirements that must be satisfied by the designer so that the designed structure will have minimum acceptable level of safety.
Some highlights of his presentation were:
   Structure has three filters- Stiffness (K), Mass (M) of the material and the damping coefficient of the material (C).
   Structural flaws and defects can be eliminated by quality control and inspection.
   Adverse effect on structure is time, over-loading, human errors and low quality of materials.
   On the uncertainties- divided into 2 parts:(a) Aletory - Data based
                                                                               (b)Epistemic- Knowledge based
   Two types of probabilities: Objective and Subjective.
   Design Philosophy - In Allowable stress design - resistance must be greater than load. Load factor design where the loads must be multiplied by 1.5. R=strength and S=load if R>S it is safe, R<S- fails, if R=S- limit state.
   Concepts of reliability - In reliability we have to determine performance function, concepts of reliability index.
Dr. Devaraj addressing the participants of workshop

Session 2: Reliability Analysis of Cable Stayed Bridges by Dr. R Ravindra
Dr. R Ravindra initially briefed the participants about the cable stayed bridges, its components, arrangements of cables and pattern of load transfer in cable stayed bridges. He explained on the analysis of cable stayed bridges showing the results of his PhD Thesis.

Session 3: Energy Concepts and Analysis of Plates by Dr. K U Muthu
Dr. K U Muthu explained in detail the energy concepts and analysis of plates. His presentation included the following concepts:
   The three approaches of energy methods.
   Strain energy due to buckling, shear and energy method applied to buckling.
   Calculation of load by energy method.
   Analysis of plates for different boundary conditions.
Dr. K U Muthu addressing the participants of workshop

Venue: Block 2, Seminar hall                                Day 2                                             Date: 23-02-2018

Session 4: Lateral Torsional Buckling and Codal Provisions of IS 800-2007 by Dr. Aravind H B
Dr. Aravind H B explained on the importance of stability in the design. He outlined on the elastic stability of structural systems, section classifications, torsional effect, lateral torsional
bucklingand factors affecting section slenderness.

Session 5: Stability of Beam Columns by Dr. Sunil Tengli
Dr. Sunil Tengli explained about the beam-column effect in a portal frame, detailed on the failure of short columns due to material and yielding, failure of long columns, behavior of column at ultimate load and details of design procedure of beam columns.
