Welcome

To the Home page of the Online Presence of the Engineering Consultancies from

Douglas M Logan BSc (Civil Eng) University of Strathclyde 1967

Thereafter some 2.5 years as Post Grad student in same Dept under Prof A COULL looking at the Behaviour of Variable Cross sections etc of Bridges CURVED in Plan

In Jan 1970 was appointed LECTURER in Structual Engineering in Dept of Civil Eng of University of Strathclyde :: and continued to research and teach until 1990  when I retired on ILL HEALTH Grounds

By 1975 I had set up a Consultancy dealing with Bridge Analysis ..it was called CABA  representing COMPUTER AIDED BRIDGE ANALYSIS ..but some became CABA{ECOSSE}  

After Retiring from the University continued with personal research into simplified methods of analysis of many forms of Bridge Decks ...and other type of Structures

Thus in the Early 1990s expanded the scope to cover more General Structures and hence formed 3S Group .... STRUCTURAL SIMULATION SOFTWARE and later the name became modified to 3S Group{Alba}

In about the year 2000 I felt that more interaction with clients was necessary and hece I started to think about the ONLINE presence for PRESENTATION of material in the form of Onine Courses ( PowerPoint and You Tube) and other activities thus IngDMLogan.net was set up with this being the starting PORTAL
