摘要

隨著經濟發展、國民所得提高，各種大型、複雜結構相繼的被推出，它們的共同特點是施工規模大、範圍廣、時間長、過程複雜。在工程建設規模迅速發展的同時，施工事故也日益增多，嚴重影響生命財產和工程建設進度。
為了希望能夠更直接、有效的模擬施工行為，本文嘗試利用向量式運動分析建立由梁、桿構件組成結構的施工模擬程序，模擬結構施工的幾何、載荷和束制隨施工進行的力學行為。
以向量式有限元素法分析模擬問題時，構件點的運動和結構單元的內力計算獨立，不需要組建結構單元和整個問題的勁度矩陣，只需要知道每個結構單元的力-位關係，並進行對應的內力計算和構件點的內力疊加即可，因此非常方便數值模型或材料實驗關係的引入，並且也非常適合幾何、載荷和束制隨時間改變的模擬。

With economic development, national income get better, a lot of large and complex structure successive built, the common feature of those are the construction of large-scale, wide range, long time, complex process. When the construction projects develop rapidly, there are more construction accidents increasingly, effect life and construction progress.
The desire to be able to be more direct and effectively simulate the behavior of construction, this paper will attempt to employ the vector form intrinsic finite element method to analysis and establish the composition of construction simulation program from the beam and rod member, simulate the structural construction of geometry, loads and restrained conditions with the construction of the mechanical behavior.
When we employ the vector form intrinsic finite element method, the calculation of the motions and structure elements in component points are independent, does not require the formation of structural units and the whole question of those stiffness matrices, each structural unit of the force - displacement only need to know, and the corresponding internal force calculation and component points of the internal forces superimposed, therefore it’s very convenient to introduce the numerical models or material of the experimental relationship, and that’s also very suitable to simulate the geometry, loads, restrained conditions with time change.
