［摘要］石油科技國際研發(fā)中心由四個區(qū)組成，設計時根據(jù)建筑布局及高度，合理設置防震縫，將整個建筑分為6個形狀規(guī)則的單獨結(jié)構(gòu)單元，并進行了詳細的計算與分析。多功能廳等多個大空間的平面尺寸及使用荷載均較大，最大達33-6m×42m，同時結(jié)構(gòu)高度受到很大限制，為滿足建筑使用需要，采用了預應力技術(shù),設計時進行了詳細的方案優(yōu)化及計算分析，合理地布置預應力鋼筋，取得了很好的效果。建筑在2層、3層設置了6個連橋連接各個區(qū)，最大跨度達49-7m。經(jīng)過多個方案對比分析，采用一端固定一端滑動的連接方式與兩端主體結(jié)構(gòu)連接，通過詳細的計算分析和構(gòu)造措施確保其安全。設計理念可供類似工程參考。

Abstract:International Research Center for Petroleum Science and Technology is made up of four zones. According to the layout and height of the building, the building was rationally provided with several seismic joints. The whole building was divided into 6 individual buildings with regular shapes and was calculated and analyzed in detail. The plane size and load of some big span rooms, such as multi-function hall, were large. The largest size was 33-6×42 meters，and the height of the structure was limited. In order to meet the needs of building construction, prestressed technology was adopted. During the design, detailed scheme optimization and calculation analysis and reasonable arrangement of the prestressed reinforcement were carried out, and good effect was achieved. The second and third floor of the building was equipped with six corridors connected to each district. The maximum span of the connecting gallery is 49-7 meters. By comparing and analyzing, the connection mode with one end fixed and one end sliding was adopted to connect with the main structure. Detailed structural analysis and construction measures were taken to ensure building safety. The design concept can provide reference for similar projects.
Keywords:prestressed beam; bonded prestressed structure; large span corridor; sliding support
