External T-shaped steel symmetrical reinforcing structure of existing steel pipe column
An external T-shaped steel symmetrical reinforcing structure of an existing steel pipe column comprises a beam column joint arranged on the existing steel pipe column, wherein the portion, below the beam column joint, of the existing steel pipe column is a lower column. The existing steel pipe column above the beam column joint is an upper column, the lower column and the upper column are provided with a plurality of pieces of external T-shaped steel in the column height direction, the external T-shaped steel is arranged in an axial symmetry mode at equal angles, the arrangement angles of the external T-shaped steel on the sections of the lower column and the upper column are kept in one-to-one correspondence, a plurality of pieces of beam column joint stiffening T-shaped steel are arranged on the beam column joint, and the arrangement angle of the beam-column joint stiffening T-shaped steel is consistent with that of the external T-shaped steel; and stiffening ribs are symmetrically arranged on a frame beam connecting web of the beam-column joint. According to the method, the existing steel pipe column is utilized and is symmetrically reinforced through the external T-shaped steel, so that the section characteristics of the existing steel pipe column can be effectively increased, including the inertia moment, the resisting moment and the area of the section, and the bearing capacity and the lateral stiffness of the reinforced steel pipe column are remarkably improved.
一种既有钢管柱外置T型钢对称加固结构，包括设置在既有钢管柱上的梁柱节点，所述梁柱节点以下的既有钢管柱为下柱；所述梁柱节点以上的既有钢管柱为上柱，所述的下柱和上柱沿柱高方向设置有若干个外置T型钢，外置T型钢轴对称等角度设置，且外置T型钢在下柱、上柱截面上的布置角度保持一一对应，梁柱节点上设置有若干个梁柱节点加劲T型钢，所述的梁柱节点加劲T型钢的布置角度与所述的外置T型钢一致；所述梁柱节点的框架梁连接腹板对称设置加劲肋。本发明利用既有钢管柱，通过外置T型钢对称加固，可有效增大既有钢管柱的截面特性，包括截面的惯性矩、抵抗矩和面积，使加固后的钢管柱承载力和抗侧刚度显著提高。
