双曲扁壳可用于水电站地下厂房或入防工程,其计算方法现有多种,无论何种方法,均需专门的计算公式和专门的图表手册,通过较长的计算程序,方可得到正确答案。就此问题,现在我们采用一般结构手册,来解决双曲扁壳的设计问题。如图(一)我们认为双曲扁壳体是由两向拱断面组成,在壳体的两个方向,各取断面,计算时单独取出脱离拱考虑,取出来的拱,假定是无铰拱组成的壳体;壳体四边边缘侧构件,为两向拱的固端支座,一向
Hyperbolic flat shells can be used in underground powerhouses of hydroelectric power stations or in defense engineering. There are many methods for their calculation. No matter which method, special calculation formulas and special chart manuals are required. Only through a long calculation program can you get correct results. answer. For this problem, we now use the general structure manual to solve the design problem of the hyperbolic flat shell. As shown in Figure (a), we believe that the double-curvature flat shell is composed of two-way arch sections. In both directions of the shell, each section is taken out. The calculation is taken separately and taken out of the arch. The taken out arch is assumed to be a hingeless arch. The shell is composed of four sides of the shell edge side member, for the two-sided arch fixed end support, always
