满意优化解

本文给出几项在有限的具体方案中求出实用上的优选满意解．阐述了预应力混凝土梁中预应力钢筋较合理的配置，进行了有关试验观测和钢筋混凝土方板优选配筋的试验研究，并都给出了一些细节．此外，述及了国内对纵横向框架设计的经济比较．介绍了采用3种不同形式连粱的4层框架比较试验研究，带竖向通缝和不同布筋的竖向缝槽及不同配筋的钢筋混凝土低剪力墙的试验研究，在框架和剪力墙的试验研究中还包括了对结构延性的研究．以上4项试验研究都是在东南大学进行的．最后简述了国外对普通结构设计和具有可持续性的拆卸设计的比较．

Satisfactory optimum solutions

This paper gives some practical satisfactory optimum solutions in several concrete proposals. Here both the more reasonable arrangements of prestressing steel in prestressed concrete beams with relevant observation also conducted in tests, and the experimental study of the better reinforcements in square reinforced concrete slabs, are given with some details. Additionally, the economic comparison of the design of longitudinal and transverse frames finished in this country is mentioned. The comparative experimental study of 4-story frames with 3 different coupling beams, the experimental study of low reinforced concrete shearwalls with vertical slits throughout and with vertical keyways in different reinforcements are also introduced, in both of these two studies the ductility of structures is also included. The four studies mentioned above were all conducted at Southeast University. Finally, the comparison of ordinary design and design for disassembly with sustainability put forward in a foreign country is stated simply.
