［摘要］主要介紹廣州市交通信息指揮中心結(jié)構(gòu)設(shè)計的關(guān)鍵技術(shù)，對鋼管混凝土核心柱的相關(guān)設(shè)計問題、環(huán)梁的計算及構(gòu)造、菱形鋼筋的設(shè)計及構(gòu)造、牛腿的設(shè)計、屋頂大跨度設(shè)計、現(xiàn)澆混凝土空心樓蓋設(shè)計等核心問題進行了詳盡描述。針對剪力墻平面外抗彎承載能力的計算及錨固長度不夠的問題，給出設(shè)置環(huán)梁的設(shè)計方法，并給出了設(shè)計公式。結(jié)果表明，采用單向布置的結(jié)構(gòu)方案能解決荷載較大的大跨度結(jié)構(gòu)受力問題；采用牛腿的轉(zhuǎn)換方式能有效地解決上下錯位的框架柱結(jié)構(gòu)的傳力問題。

Abstract:Key technologies in structural design of Guangzhou Traffic Information Command Center were mainly introduced. Detailed descriptions on some major problems in designing were provided such as the design of concrete-filled steel tubular core column, calculation and construction of the circular beam, design and construction of the diamond steel bar, design of bracket, design of large-span roof as well as design of cast-in-situ concrete hollow floor. The design method and the design formula of setting circular beam were given for the calculation of the lateral flexural bearing capacity of shear walls and the insufficient anchorage length. The results show that the structure scheme of unidirectional layout can solve the force problem of large-span structure with large load. The method of bracket conversion can effectively solve the force transmission problem of the frame column structure with upper and lower dislocation.
Keywords:circular beam; diamond steel bar; bracket; concrete hollow floor
