Computation of vertical stress in soil beneath loaded area is greatly simplified by influence chart, which was proposed by N. M. Newmark in 1942.The main purpose of this paper is to present a method to modify the Newmark's chart. Instead of the concentric circles in the original chart, concentric squares are used. The latter is more convenient to estimate number of blocks. Further, a so-called "influence value curve" is introduced to avoid different tracings for different depths at which stress is computed.The...

推算地基土壤由於建築物重量所引起的應力和變形,是估計建築物沉陷的必經步驟。利用感應圖的計塊法來推求應力和變形,紐馬克教授曾先後於1942年和1947年發表。這種方法,特別是以感應圖求土壤中的垂直應力,當遇到不規則形的建築物基礎時,或研究各基脚相互間的應力影響時,工程界採用的很多。本文主要內容是對感應圖圖解法提出下面四點改進的方法,以便利地基和基礎的設計工作:一.原方法的應力感應圖由若干同心圆形圈所組成,本文改用許多同心正方形,使估計不成整塊的塊數時,比較準確。二.筆者製成“感應值曲線”。當需要計算不同深度處的垂直應力,基礎平面圖祇需根據其中某一深度為比例尺繪製,其他深度處的垂直應力,可根據感應值曲線求得。這樣,避免原方法中每個深度耍繪不同的基礎平面圖以及每次計點塊數的麻煩。三.當地基土壤屬於不允許横向膨脹狀態,本文根據e-p曲線所得的壓縮公式,製成多條曲線,以便利計算。四.當地基土壤可假定屬於彈性狀態時,筆者製成正方形的變形感應圖,以便利彈性地基上具有不規則形基礎的建築物的沉陷計算。

A nonlinear elastic-viscoplastic constitutive relation is used to simulate the dynamic behavior of metal structural meterials. A finite element formulation for inelastic earthquake response analysis of shear space frame structures considering horizontal-torsional coupling vibra- tion is developed. The plastic yield condition of frame column is rep- resented in stress resultants. The need to determine the state of ele- ments either elastic or plastic and to verify either loading or unload- ing cccuring at each step in usual elasto-plastic dynamic analysis is eliminated. P-△ effect ■s taken account in constitutive relation of column element. An implicit second-order Runge-Kutta scheme in conj- uction with a Newton-Raphson iteration technique is used for sovlving nonlinear equations of motion.
