Analysis of Structural Instrumentation Data for Lock and Dam Number 1, Red River

Abstract

This report contains an evaluation of data obtained from instrumentation of Lock and Dam No. 1 on the Red River and corresponding structural analyses. This work was undertaken because of unexpected heavy silt buildup during the spring of 1985. The computer program, CUFRAM, was used for the structural analyses. The lock monolith L-10 was used for the comparisons in this report. Measured soil pressures were used as input pressures to CUFRAM. Member forces obtained from the analyses were compared with forces calculated using the measured strains in the reinforcing steel. The calculated moments were shown to have relatively good agreement with moments from the measured strain data. However, axial forces obtained using the same procedures were significantly different. The reason for this discrepancy is discussed. Keywords: Locks waterways; Structural analysis; Loads forces; Red River waterway Louisiana; U-frame structures; Structural loads.
