It is shown in the paper that this problem is similar to that of a continuous curved beam on rigid supports and can be most easily solved by method of special slope deflection equations. The formulas for computing load and shape constants being necessarily long, a number of tables of useful functions have been prepared to aid in a quick analysis and a typical example is given. The theory and functions presented in the paper...

    The analysis of stepped beams on spring foundation is a problem of practical importance. It is shown in the paper that this problem is similar to that of a continuous curved beam on rigid supports and can be most easily solved by method of special slope deflection equations. The formulas for computing load and shape constants being necessarily long, a number of tables of useful functions have been prepared to aid in a quick analysis and a typical example is given. The theory and functions presented in the paper are also applicable in analyzing other problems with same mathematical nature, such as the problem of axisymmetrical bending of cylinders with nonuniform wall thickness.

    本文討論彈性地基上的阶形梁的計算問題。应用結構力学上“桿件常数”的观念,这个問题可以簡捷地获得解决。文中除举例說明計算步驟外,並供給必要的函数表,使这些常数能够迅速求出。这些函数同样可以用来解决数学上类似的問題,例如变截面圓筒的軸对称受弯问題。

    高樁古岸壁的结构计算是相当繁重的。从理论观点来看,苏联史莫洛金斯基提出的方法是最有意义的。但是由于它的计算工作太复杂,在实际工程设计中很难广泛应用。 本文基于结构力学中混合法的原理提出一个计算方法,它大大地精简了计算工作,而仍保持史氏方法的精确度。

    在桥樑和房屋等结构中,不论结构物是由钢或钢筋混凝土所制成,它的构件截面在整个体系之内,特别是在一个跨径之内,每每是变化的。设计这种超静定的结构时,一般是根据经验或类似的参考资料和便利于力学计算的要求,先假定构件截面的函数,作力学计算。按照由此算得的内力作出截面设计之后,重新进行力学计算。必要时在再次修改截面之后,仍须复核一次力学计算。这种反复的计算过程,其繁琐费时是为实际工作中的结构力学工程师所深深感到的。因此各方面曾致力于为变截面构件的计算编制实用的表格和实用的计算公式[1],以减轻计算工作。本文也是为减轻这种计算工作的一种尝试。为了这个目的,我们提出这样的问题:假定某一个超静定的结构物,用便利于力学计算的构件截面函数作了第一次力学计算之后,构件的截面变更了。试问能否在第一次计算的基础上求出截面变更所引起的内力数值的变更?研究的结果可以简要归纳成三点:第一,x点的构件截面的变更对于任一截面的内力z的影响,可以用“截面变更对内力的影响线Ψ_z(x)”来表示,从而可以求出在一定的荷载情况下截面的变更对内力z引起的变更△z。第二,确定了各处的构件截面变更之后,可以求出任一内力z的荷载的影响线η_z的变...
