以结构力学课程无纸考试为出发点，分析了主观考试题在线答题与计算机评定的难点问题，提出了引导式主观考试题型的交互答卷与自动评判的程序方法。在VB软件平台下，以图乘法计算结构位移问题为例，描述了结构力学课程主观题型在线交互答卷与成绩自动评判的程序机理，给出包括静定结构弯矩图绘制、图乘法计算结构位移、超静定结构力法与位移法求解和结构固有特性问题在线答题与自动评判实例。此研究解决了结构力学课程主观题型的无纸化考试与自动评判问题，其研究思路将为力学等工程类课程主观题型的考试与评定提供有效的程序方法。

In this paper, from paperless examination about structural mechanics curriculum, online answer and computer evaluation difficulties about subjective examination questions are analyzed. Program method about guided subjective examination questions and automatic evaluation is proposed. In the VB software platform, with diagram multiplication method computing structure displacement problem, subjective questions online interactive answer and score evaluation mechanism about structural mechanics are described and practical examples are given. Online answer and automatic evaluation result about examination paper include statically determinate bending moment diagram, diagram multiplication method,statically indeterminate structure force method and displacement method, structure inherent characteristics are listed. The method will be provided for paperless examination of mechanical engineering courses.
