CONCEPT OF STRUCTURAL CONTROL

IN AN IDEAL SITUATION, COMPLETELY SAFE STRUCTURES CAN BE DESIGNED IF EXACT INFORMATION IS KNOWN CONCERNING LOADS AND STRENGTHS INVOLVED DURING THE LIFE TIME OF THESE STRUCTURES, AND EXACT METHODS OF STRUCTURAL ANALYSIS ARE AVAILABLE. IN THE REAL WORLD, UNCERTAINTIES EXIST IN THIS INFORMATION AS WELL AS IN THE METHOD OF ANALYSIS. TO ACCOUNT FOR THESE UNCERTAINTIES, VARIOUS FACTORS OF SAFETY HAVE BEEN USED IN THE DESIGN OF STRUCTURES. THE OBJECTIVE HEREIN IS TO PRESENT THE CONCEPT OF STRUCTURAL CONTROL AS AN ALTERNATIVE APPROACH TO THE SAFETY PROBLEMS OF STRUCTURAL ENGINEERING. PERTINENT POINTS OF THE CONTROL THEORY ARE REVIEWED ALONG WITH CERTAIN PIONEERING WORK IN THIS DIRECTION. THE PRACTICALITY OF THIS CONCEPT IS ILLUSTRATED WITH AN EXAMPLE USING ANALOG PARALLEL LOGIC DEVICES. MORE WORK IS NEEDED IN ORDER TO APPLY THE CONCEPT OF STRUCTURAL CONTROL TO COMPLICATED STRUCTURES SUCH AS EXTREMELY TALL BUILDINGS OR LONG BRIDGES SUBJECTED TO UNCERTAIN DYNAMIC LOADS SUCH AS WIND AND EARTHQUAKE EXCITATIONS.
