宁波市镇海区某办公楼为高层框架结构,裙房平面不规则,存在局部框架梁转换。结构设计时通过设置抗震缝的办法解决平面不规则。对部分大跨度转换梁采用预应力混凝土梁控制其挠度和裂缝。基础设计时,采用提前试桩确定本工程的桩极限承载力,底板采用梁板式,简述该办公楼的设计过程和分析结果。 Zhenhai District, Ningbo City, an office building for the high-rise frame structure, irregular podium floor, there is a local frame beam conversion. Structure design by setting the seismic seam approach to solve the plane irregularities. Prestressed concrete beams are used to control the deflection and cracks of some long-span conversion beams. The basic design, the use of pre-test pile to determine the ultimate bearing capacity of the project, the floor plate beam, the design of the office briefing process and analysis results.
