Correlation of Theoretical and Experimental Data for Highway Bridges


Book Description

A computer program analytical routine 'SSAP-2' is used to correlate a theoretical finite element analysis with experimental results for three typical two-lane multi-span girder and slab highway bridges in Tennessee. The programmed response for a fourth bridge is also included. All three bridges gave excellent correlation between predicted and experimental responses for deflection and moment distribution of the HET-70 loading to the main carrying members of the bridge. It is concluded that maximum stresses induced by future unique heavy military loads can be compared on a timely basis with the highway bridge structure's load carrying capability by use of the computerized theoretical method.







Composite Steel Structures


Book Description

The constant need for cost-effective structural forms has led to the increasing use of composite construction, and a substantial amount of research effort is currently being spent in developing techniques for combining concrete and steel effectively. Significant economies in this form of construction have been observed, especially in bridges and building floors. Codes of Practice on composite construction are being revised in the UK and in Europe, in the light of the substantial amount of knowledge that has been generated in recent years. An International Conference organised by the Department of Civil and Structural Engineering, University College, Cardiff, UK, with the specific objective of discussing all types of metal structures in an integrated way, provided a forum for the dissemination of new concepts and for reviewing developments; the expectations of the organisers have been amply justified and exceeded by the level of international response to the call for papers. This volume contains 17 papers on composite steel structures, presented at the Conference, many of which were by well-known experts in their respective fields.
