COMBINED STEEL BATTER PILE FOUNDATION METHOD AND ITS SEISMIC PROPERTIES

PIERS, WITH LONG COMBINED STEEL BATTER PILES DRIVEN INTO VERY WEAK GROUND, HAVE BEEN CONTRUCTED. AS THERE ARE FEW CASES OF THIS TYPE OF STRUCTURE COMPLETED AND DATA RELATED TO ITS ANTI-SEISMIC BEHAVIOR ARE FEW, EXPERIMENTAL ANALYSIS ON ITS STATIC AND DYNAMIC BEHAVIOR WAS PERFORMED, BASED ON THE DATA OBTAINED AT EACH STAGE OF THE CONSTRUCTION. STATIC VERTICAL LOADING TESTS PROVED THE RELIABILITY OF THE FOUNDATION, BUT THE RESULTS OF STATIC HORIZONTAL LOADING TESTS AND DIRECT HORIZONTAL VIBRATION TESTS SHOWED A CONSIDERABLE DIFFERENCE FROM THOSE CALCULATED ON THE CONVENTIONAL DYNAMIC MODEL OF STRUCTURE GROUND RELATION. OTHER TESTS REVEALED THAT THE RESULTS OF INDIRECT HORIZONTAL VIBRATION TEST, WHICH VIBRATES THE GROUND INSTEAD OF THE STRUCTURE, GIVE A VERY DIFFERENT RESPONSE COMPARED WITH THE DIRECT HORIZONTAL VIBRATION TEST, AND THAT THE RESULTS ALSO DIFFER ACCORDING TO THE METHOD OF VIBRATION. /JRA/
