矩阵位移法  按位移法的基本原理运用矩阵计算内力和位移的方法。是结构矩阵分析方法中的一种,其基本未知数是结点位移,由于矩阵位移法较矩阵力法更适宜编制通用的计算程序,因而得到了更为广泛的应用。    结构矩阵分析方法首先把结构离散成有限数目的单元,然后再合成为原结构,因而也属于有限元法。矩阵位移法常用的单元形式为一直杆。对于曲杆,如拱结构,虽然也可取曲杆作为单元,但单元分析较烦,为简化起见,可将它化成折线来处理,每一直线段作为一单元。当单元承受非结点荷载时,可用等效结点荷载代替。其方法是将单元间的分界结点作为固端求出固端反力,然后反其向作用在结点上。    根据结构变形后要满足几何方面的相容条件(变形条件),结点位移矩阵与杆端位移矩阵之间存在关系式           =          (1)式中表示对的变换矩阵。    杆端位移矩阵与杆端力矩阵之间的关系式为           =m          (2)式中m称为未装配结构的刚度矩阵,它等于各单元刚度矩阵(i) 作为子块的对角矩阵。 其元素可直接按结点单位位移引起的反力而求得。由于单元坐标并不一定是整体结构坐标,因而求得的单元刚度矩阵(i) 需通过坐标变换转化为整体坐标下的单元刚度矩阵。    根据结点作用力与汇交于该结点的杆端力保持平衡关系,可以得到杆端力与结点作用力的关系式为            =         (3)式中为杆端力矩阵 对结点作用力矩阵 的变换矩阵。根据虚功原理,可得=T。    根据上面三式,可以得到            =K         (4)            K=Tm        (5)式(5)K称为已装配结构的刚度矩阵或整体刚度矩阵。    通过式(5)获得总刚度矩阵K的方法称为刚度法。因为位移变换矩阵的阶数相当高,运算中须占大量的存贮单元,因而在组合整体刚度矩阵时,常采用直接把单元刚度矩阵的元素输送到K中的直接刚度法,该方法是将各单元中相同脚标的元素直接相加而组成整体刚度矩阵。在单元刚度矩阵中,对于近端结点刚度矩阵系数kjj,由于汇集于该结点j的所有单元都可作出贡献,因而在整体刚度矩阵中可有若干项相加,即,为汇集于j结点的所有单元。由于它不必通过式(5)进行计算,运算方便,因此其应用比刚度法更为广泛。    由于支座约束方向的结点位移通常为零或为已知值,因而可将全部结点位移分为两部分,一部分是不受支座约束的位移r,另一为沿支座约束方向的结点位移R。由此(4)式变成        展开上式得                  (7)                 (8)当R=0时(7)式变成:          r=Krr          (7′)式中Kr 为已装配结构相应不受支座约束的位移的刚度矩阵,实际上即为一般位移法基本方程中的系数矩阵K,该矩阵亦可直接按柔度矩阵求逆而得到。而r即为一般位移法基本方程的自由项矩阵(一般位移法中,K与在方程同一边,因而r与差一符号)。因而(7′)式即为位移法基本方程的矩阵表达式。    根据(7)或(7′)式即可求出r。再由(1)、(2)式即可求得杆端力,实际杆端力a应再叠加单元上非结点荷载引起的固端力f。第i单元的实际杆端力应为         a(i)=(i)(i)+f(i)        (9)    矩阵位移法计算杆端力的步骤为:①划分单元,求出等效结点荷载;②求单元刚度矩阵(i),并转换为整体坐标的单元刚度矩阵;③由(5)式或直接刚度法求出整体刚度矩阵K;④求出Kr和r;⑤由(7′)式求出结点位移r,再由(1)、(2)式求出杆端力,实际杆端力应再叠加f, 即由(9)式确定。
