    Slenderness Ratio Effect on the Eccentric Compression Performance of Chamfered Laminated Bamboo Lumber Columns

    Ke Zhou1,2, Haitao Li1,2,*, Assima Dauletbek1,2, Dong Yang1,2, Zhenhua Xiong3, Rodolfo Lorenzo4, Kun Zhou5, Ileana Corbi6, Ottavia Corbi6

    Journal of Renewable Materials, Vol.10, No.1, pp. 165-182, 2022, DOI:10.32604/jrm.2021.017223

    Abstract Eccentric compression tests on 15 chamfered laminated bamboo lumber (LBL) columns with a height ranging from 600 to 3000 mm were conducted in order to study the eccentric mechanical performance. The failure of all specimens was caused by the crack of bamboo fiber in the tensile region. When the ultimate strength was reached, except specimens with a height of 600 mm, all other specimens could bear large deformation, showing good ductility. The lateral displacements of the specimens under eccentric compression were approximately parabolic in the direction of column height. The ultimate bending moment of LBL columns with different slenderness ratios… More >

    Behavior of High Strength Concrete Filled Square Steel Tube Stub Columns with Inner CFRP Tube Under Biaxial Eccentric Compression

    Zhijian Yang1, Guochang Li1,*, Yan Lang2, Zengmei Qiu1

    CMES-Computer Modeling in Engineering & Sciences, Vol.127, No.1, pp. 273-290, 2021, DOI:10.32604/cmes.2021.014606

    Abstract This paper studies the contribution of CFRP (carbon fiber-reinforced polymer) to the mechanical behavior of high strength concrete-filled square steel tube (HCFST) under biaxial eccentric compression. The new type of composite member is composed of an inner CFRP tube and an outer steel tube with concrete filled in the two tubes. The finite element analysis was made by ABAQUS on the behavior of high strength concrete filled square steel tubular columns with inner CFRP circular tube subjected to bi-axial eccentric loading. The results obtained from the finite element analysis were verified with the experimental results. In addition, the load-deflection curves… More >
