Research on Eccentricity Magnification Factor of Eccentric Compression Lightweight Aggregate Concrete Member
In view of the drawbacks of eccentricity magnification factor formula in current lightweight aggregate concrete code in practice, in this research, according to whole-process theoretical analysis and considering second order moment, sectional curvature, lateral deflection and corresponding eccentricity magnification factor at control section for circular cross-section eccentric compression member under different end moment are derived. By comparing them with experimental results, eccentricity magnification factor calculated in this research are demonstrated to be feasible and reliable, which can provide beneficial reference for structural design in practice.
