一、前言对于20层以下的高层建筑,框架或框架——剪力墙结构是我国当前采用的主要结构形式之一。由于高层建筑需要一定的埋深,以满足地基强度和稳定性要求,因而箱形基础又是高层建筑普遍采用的基础型式。《箱基规程》(JGJ6—80)规定,计算箱基整体弯曲所产生的弯矩时,应考虑上部框架结构与箱形基础的共同工作,并推荐Meyerhof的等代梁法。笔者认为,该法尚有可商榷之处,除地基反力确定尚欠足够的理论与实测依据外,上部结构总的
I. INTRODUCTION For high-rise buildings below 20th floor, the frame or frame—shear wall structure is one of the main structural forms currently adopted in China. As the high-rise building needs a certain depth of burial to meet the requirements of foundation strength and stability, the box-shaped foundation is the basic type commonly used in high-rise buildings. “Box Foundation Regulations” (JGJ6-80) stipulates that when calculating the bending moment generated by the overall bending of the box foundation, consideration should be given to the joint work of the upper frame structure and the box foundation, and the Meyerhof equivalent beam method is recommended. The author believes that there are still areas where this law can be discussed. Except for the determination of ground-based counterforce, it still owes enough theoretical and practical evidence to determine the total number of superstructures.
