TENSILE STRUCTURES – INTRODUCTION

Tensile Structures Tension roofs or canopies are those in which every part of the structure is loaded only in tension, with no requirement to resist compression or bending forces. Classes of Tensile Structures 1. Membranes – The structural membrane acts also as the ...

STRUCTURAL EVALUATION PROCESS

STRUCTURAL EVALUATION PROCESS This procedure is applicable for conventionally reinforced cast-in-place concrete, precast-prestressed concrete and post-tensioned cast-in-place concrete. The evaluation of an existing concrete building is usually performed for stability, strength, safety and future expected life. Evaluation of a structure may ...

TOPOLOGY OPTIMIZATION OF STRUCTURES

TOPOLOGY OPTIMIZATION OF STRUCTURES USING DENSITY DISTRIBUTION APPROACH It is of great importance for the development of new products to find the best possible topology or layout for given design objectives and constraints at a very early stage of the design ...

FATIGUE STRENGTH OF RIVETED AND CORRODED STRUCTURES

The fatigue strength of riveted members is relatively insensitive to the rivet pattern or type of detail (cover plate details, longitudinal splice plates, and angles or shear-splice details). A major advantage of riveted (or bolted) members is that they are ...

DESIGN FOR TERRORIST ATTACK FOR NEW CONSTRUCTION

Site planning – Physical layout and physical security aspects are to be considered. Surveillance is to be provided for avoid terrorist attack. By providing access controls and physical barriers. By restricted parking near the building Deep buried structures are safer. Walls ...

ARCHITECTURAL FEATURES & EARTHQUAKE

Importance of Architectural Features The behaviour of a building during earthquakes depends critically on its overall shape, size and geometry, in addition to how the earthquake forces are carried to the ground. Hence, at the planning stage itself, architects and structural ...

BEHAVIOUR OF BOX GIRDER BRIDGES

A general loading on a box girder, such as shown in fig 1 for single cell box, has components which bend, twist, and deform the cross section. Thin walled closed section girders are so stiff and strong in torsion that ...
