砖混结构房屋基础的优化设计

砖混结构房屋基础一般采用条形基础,按各墙体承受的荷载分别计算基础宽度。由于墙体的共同工作,应按基础底面压应力的分布特点确定基础外形方案。以基础工程造价最低为目标,以基础外形尺寸为设计变量,以地基承载力和变形控制为约束条件建立数学模型,用 MDOD 算法进行优化计算,寻求经济合理的基础方案,可直接用于基础设计。

OPTIMIZING DESIGN OF BUILDING FOUNDATION WITH BRICK MASONRY STRUCTURE

Strip foundation is general used in the foundation of brick masonry structure bearing load,which width is calculated according to the bearing load under wall.The plan of the foundation shape should be designed by the compression stress distribution at the foundation bottom,for the coordination action of the walls.So I suggest an optimizing design method,which aims for the lost cost of foundation work,uses the outline size of the foundation as design parameter,uses the ground bearing capacity and deformation control as constrained condition to make up an mathematical model,then calculate optimizing with algorism of MDOD,so we can find an economic and gust foundatinn plan,to directly use for foundation design.
