论文部分内容阅读
近年来,我们收到许多来信,要求我们增设学生专栏。为了满足这一要求,本刊今年新开辟了“学生之友”专栏。本专栏以丰富学生的课外生活、配合学校教学为目的,主要介绍与学习密切相关的结构设计、施工、建筑设计等方面的实践经验及学习中一些容易误解的问题;介绍有关的设计资料和优秀的学生作业,以及学习中的心得体会……等。对这个专栏有什么要求和建议,请同学们来信,并欢迎同学们积极投稿。让我们同心协力,把这个专栏办的生动、活泼,使它名符其实成为学生之友。同学们在学习砖石结构时,都知道,墙体加设壁柱,可以提高结构刚度、降低构件的高厚比值,从而增加构件的承载能力。那么,是不是在任何情况下,加设壁柱都能提高构件的承载能力呢?初学者的回答往往是肯定的,而正确的回答应是“不一定”。为此,我们在这期的“学生之友”专栏中刊登了“设置砖壁柱应注意的问题”。文章介绍了如何正确设置砖壁柱才能使构件的承载能力得到提高,愿同学们能从中得到收益。——编者
In recent years, we have received many letters requesting us to add a student column. In order to meet this requirement, the journal has opened a new “Friends of Students” column this year. This column aims to enrich students’ extra-curricular life and coordinate with school teaching. It mainly introduces practical experience in structural design, construction, architectural design, etc., which are closely related to learning, and some misunderstood questions in the course of study; introduction of relevant design materials and excellent Student work, as well as learning experience... and so on. What are the requirements and suggestions for this column? Please send letters to the students and welcome the students to contribute actively. Let us work together to make this column lively and lively, making it a student friend. When students learn about masonry structures, they all know that the addition of pilasters to the wall can increase the rigidity of the structure and reduce the height-to-thickness ratio of the components, thereby increasing the bearing capacity of the components. Then, is it possible that, in any case, the addition of pilasters can increase the carrying capacity of the components? The answer for beginners is always affirmative, and the correct answer should be ”not necessarily”. For this reason, we have published the “Problem to Set Attention to Brick Pillars” in this issue of the “Friends of Students” column. The article describes how to properly set up the brick stanchion in order to improve the carrying capacity of the components. It is hoped that the students will benefit from it. --editor
