【摘要】：某電廠煤場封閉式干煤棚橫向跨度110m、長度229m、矢高35.4m,鋼結(jié)構(gòu)采用索拱桁架結(jié)構(gòu),剖面形狀為三心圓,上部為倒三角形桁架,下部加設(shè)預(yù)應(yīng)力拉索,支座節(jié)點(diǎn)采用半球鉸支座,兩側(cè)山墻平面封閉。在設(shè)計(jì)時(shí)對結(jié)構(gòu)原理進(jìn)行了研究,并對結(jié)構(gòu)進(jìn)行整體穩(wěn)定分析,同時(shí)對索拱桁架結(jié)構(gòu)與柱面網(wǎng)殼結(jié)構(gòu)進(jìn)行經(jīng)濟(jì)指標(biāo)比對,論證了索拱桁架在大跨度干煤棚結(jié)構(gòu)中應(yīng)用可行性。
[Abstract]:The closed dry coal shed of a power plant has a transverse span of 110m, a length of 229m, and a sagittal height of 35.4m.The steel structure adopts cable-arch truss structure, the section shape is triaxial circle, the upper part is an inverted triangular truss, and the lower part is equipped with prestressed cable. The support node adopts the hemispherical hinge bearing and the two sides of the gable wall are closed in plane. The principle of the structure is studied in the design, and the overall stability of the structure is analyzed. At the same time, the economic indexes of cable arch truss structure and cylindrical reticulated shell structure are compared, and the feasibility of application of cable arch truss structure in long span dry coal shed structure is demonstrated.
