平房浇顶有二道承重粱中间一道十字交差粱高五十宽二十四无承重柱子，如接二层还添加承重立柱吗，民房
我有更好的答案
主要是钢筋结构，如果钢筋笼是标准的立体框架笼是可以不要承重柱
你那是老房加盖吗
是的已有六年了

出门在外也不愁四边形钢管塔中十字交叉斜杆的平面内计算长度--《Special Structures》2004年01期
四边形钢管塔中十字交叉斜杆的平面内计算长度
Civil Engineering College of Tongji University,Shang hai 200092)
Quadrangular steel CHS tower is a type of space truss.Its main members are commonly directly welded at joints and thus the joints have great stiffness.The crossing web members can be restricted by the neighboring members when buckling.In this article the factors that influences the effective lengths of crossing web members are investigated by elasticity theory.And the relationship between the effective lengths and the factors is obtained by multiple calculation models.
