Experimental investigation and design of aluminum columns with longitudinal welds

Yun WU, Qilin ZHANG

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 3,   Pages 366-373 doi: 10.1007/s11709-011-0101-2

Abstract: This paper presents an experimental investigation of longitudinally welded aluminum alloy I-section columns subjected to pure axial compression. The specimens were fabricated using 6061-T6 heat-treated aluminum alloy. The test program included 20 column tests which were separated into 2 test series of different types of welding sections. Each test series contained 10 columns. All the specimens were welded using the Tungsten Inert Gas welding method. The length of the specimens ranged from 442 to 2433 mm in order to obtain a column curve for each test series. The observed failure mode for the column tests includes mainly flexural buckling around the minor axis and the major axis by applying support except for one column (ZP1217-1) which buckled in the local zone and some columns which failed in the weld. The test strengths were compared with the design strengths predicted by the European Code and China Code for aluminum structures. The purpose of this paper is to present the tests results of two typically longitudinally welded I-section columns, and to check the accuracy of the design rules in the current specifications.

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 2,   Pages 239-248 doi: 10.1007/s11709-011-0110-1

Abstract: Surcharge load (e.g. embankment fill) will induce settlement and outward lateral displacement, whilevacuum pressure will induce settlement and inward lateral displacement of a ground.Ideally, combination of surcharge load and vacuum pressure can reduce or minimize the lateral displacementFor the conditions investigated, the results indicate that the outward lateral displacement increasesAlso, it is shown that for a given and condition, lateral displacement reduces with the increase
