Fireproof design method for orthogonal engineering bamboo-concrete composite floor
The invention discloses a fireproof design method for an orthogonal engineering bamboo-concrete composite floor. The fireproof design method comprises the steps that the section size of the composite floor is selected, the rigidity and stress distribution of the composite floor are calculated through a gamma-method, deformation and strength at the normal temperature are checked, and the section size meeting the normal-temperature design requirement is determined; determining the fire endurance design requirement of the composite floor and the most unfavorable load combination effect design value in the fire; calculating the stress distribution of the residual section of the carbonized composite floor slab by adopting a gamma-method, and obtaining the fire endurance of the composite floor slab through iterative calculation; comparing whether the fire endurance calculation value of the composite floor is not smaller than the fire endurance design value, and if yes, determining the section size of the composite floor; if not, increasing the number of the laminates of the engineering bamboos in the composite floor; and repeating the steps until the fire endurance of the composite floor meets the design requirement, and determining the sectional dimension of the composite floor. The fireproof design method for the orthogonal engineering bamboo-concrete composite floor is scientific, accurate and effective.
本发明公开了一种正交工程竹—混凝土组合楼板防火设计方法，其包括：选取组合楼板的截面尺寸，采用γ—法计算组合楼板的刚度和应力分布，验算常温下的变形和强度，确定满足常温设计要求的截面尺寸；确定组合楼板的耐火极限设计要求和火灾下最不利荷载组合效应设计值；采用γ—法计算炭化后组合楼板剩余截面的应力分布，通过迭代计算得到组合楼板的耐火极限；比较组合楼板的耐火极限计算值是否不小于耐火极限设计值，若满足，则确定组合楼板的截面尺寸；若不满足，则增加组合楼板中工程竹的层板数量；重复上述步骤直至组合楼板的耐火极限满足设计要求，确定组合楼板的截面尺寸。本发明形成了一种科学、准确、有效的正交工程竹—混凝土组合楼板防火设计方法。
