由于轻混凝土特别是陶粒混凝土结构应用范围的扩大,有必要对超配筋陶粒钢筋混凝土双向受弯构件性能进行研究。为此,在波勒塔夫斯克工程建筑研究所进行了实验和理论研究,在研究过程中,试验了30根截面为16×24厘米、长3米的梁式试件。已经判明,在-21-75中所规定的一般原则对陶粒钢筋混凝土构件的计算是适用的。但是,当陶粒钢筋混凝±构件双向受弯时,必须进行一些与确定受压区混凝土极限强度(超配筋界限)有关的修正。所拟订出的矩形截面陶粒钢筋混凝土双
Due to the expansion of the application scope of light concrete, especially ceramsite concrete structures, it is necessary to study the properties of super-reinforced ceramic reinforced concrete bi-directional bending members. To this end, experimental and theoretical studies were carried out at the Engineering and Construction Institute of Pletavsksk. During the course of the study, 30 beam specimens measuring 16 x 24 cm in length and 3 m in length were tested. It has been determined that the general principles laid down in 21-75 are applicable to the calculation of ceramsite reinforced concrete members. However, when the ceramsite concrete coagulation ± member is bent bidirectionally, some correction must be made to determine the ultimate strength of the concrete in the compression zone (the limit of super-rebar). The rectangular section of ceramsite reinforced concrete has been drafted
