钢筋混凝土框架结构设计计算源程序，用vb开发。-reinforced concrete frame structure design source files, using Visual Basic development.

摘要：基于新修订水工结构设计规范的水工混凝土结构CAD系统，以中文Windows为操作平台，采用先进高效的VB语言和面向对象的程序设计方法，具有良好的人机交互界面.本文详细介绍水工混凝土结构CAD系统的总体设计原则以及文件系统、结构分析、素混凝土、钢筋混凝土、预应力混凝土、规范查询等功能模块的设计思-Abstract: Based on the newly revised Code for Design of hydraulic structures of hydraulic concrete

这是第5个资源，与前面几个是一通的，也可单独使用计算，都是关于钢筋混凝土设计计算的-This is the first five resources, and is a pass in front of a few can also be used on their own terms, are calculated on the design of reinforced concrete

路基可靠度计算的好文章，搞可靠度的可以下载看看。- One of the key problems of Performance-Based Seismic Design (PBSD) is how to quantify the performace objectives. Seismic damage model is an important tool for calibrating the degree of damage of structures under earthquak
