摘要

这个贡献处理的是简单的平面非对称3杆销连接桁架。给出了根据一阶和二阶理论及其他可能的线性化(即内力、反力、伸长、应力)求导和求解的途径和方法。有应用的线性和非线性方法及其通过泰勒级数的简化。最后，对各种方法的误差进行了评价和比较。

COMPARATIVE STUDY OF SIMPLE TRUSS SOLVED ACCORDING TO THE THEORIES OF 1ST AND 2ND ORDER

: This contribution deals with the simple planar asymmetric pin-connected truss with 3 members. The ways and methods of derivations and solutions according to theories of ﬁrst and second order and other possible linearizations are shown (i.e. internal forces, reactions, elongations, stresses). There are applied linear and nonlinear approaches and their simpliﬁcations via Taylor’s series. Finally, the errors of all approaches are evaluated and compared.
