混凝土预制板与地基软件

适用于从简单到复杂的混凝土楼板、任意形状和各种厚度的基础分析和设计。基础可以是筏基、条形基础或独立扩展基础的组合 1) SAFE是利用强大的基于对象建模来自动进行从简单到复杂的混凝土楼板和基础系统的分析与设计。SAFE可以分析和设计具有任意形状、各种厚度、柱顶托板、开洞、边梁和不连续的楼板和基础底板，基础可以是筏板基础、条形基础或独立基础的组合。 2) SAFE的分析是基于最新有限元分析技术进行的，它能够准确地反映出扭矩的效应；在用户自定义参数的基础上自动生成有限元网格；基础的计算模型是弹性地基上的厚板，其中单压土壤弹簧是基于地基作用的模量自动进行离散分布，可以给每个对象单独设置地基模量。 3) 软件生成钢筋布置，并且计算柱底周围的冲切剪力对基础的影响。在基于平板配筋的有限元模型中，软件提供了包括开裂性质在内的各种选项。

美国计算机和结构公司（CSI）

Ashraf Habibullah总裁在1975年建立了CSI公司。CSI在土木工程分析与设计工具软件的开发领域中被认为是全球创新者，CSI授权给美国和一百多个国家的数以千计的结构工程公司使用CSI的产品。

CSI软件开发已有30年的历史，研究开始于加利福尼亚Berkeley分校的Edward L.Wilsonat博士。1970他们第一次发布了具有革命意义的SAP程序。此后，Wilson博士被国际工程界认为是计算机辅助结构分析领域中的卓越的研究者。

每一个CSI的程序都为特定的结构形式量身定制，这就使得工程界能比使用普通程序更为有效来进行分析和设计工作。SAP是用于土木工程的软件，例如：桥梁、大坝、体育场馆、工业结构和建筑；ETABS适用于多层建筑结构的软件，例如：写字楼、公寓和医院；而SAFE则提供了对混凝土楼板和基础进行分析与设计的高效而强大的程序。

CSI不仅以尖端分析软件所闻名，而且其产品支持也是无法超越的。用户的技术支持包括：结构体系的建议、结构效应的解释，对规范各个方面阐述、对特殊模型问题参数的选取、以及对计算机结构分析和设计有关问题的阐述等。

SAFE v12 – this all-new SAFE is the ultimate integrated tool for designing reinforced and post-tensioned concrete floor and foundation systems. This version introduces versatile 3D object based modeling and visualization tools. Charged with the power of SAPFIRE this release redefines standards in practicality and productivity.

From framing layout to detail drawing production, SAFE integrates every aspect of the engineering design process in one easy and intuitive environment. Although its name is unchanged, the all-new SAFE is vastly enhanced and improved in every facet. It provides unmatched benefits with its unprecedented combination of power, functionality and ease-of-use.

SAFE v12 is available as SAFE, which includes comprehensive capabilities for reinforced concrete, or SAFE/PT, which additionally includes all post-tensioning features.

SAFE 12.3.2 Enhancements

Significant enhancements included in SAFE v12.3.2 are:

- For the Australian code AS 3600-2009, Equation 8.1.3(2) has been changed for reinforced concrete and PT design according to Amendment No. 1 to AS 3600-2009.

- The enforcement of minimum shear links now recognizes the slab separately from beam. Previously, minimum shear links were enforced for both beam and slab design. This enhancement affects all design codes.

About CSI

Founded in 1975, Computers and Structures, Inc. (CSI) is recognized globally as the pioneering leader in software tools for structural and earthquake engineering. Software from CSI is used by thousands of engineering firms in over 160 countries for the design of major projects, including the Taipei 101 Tower in Taiwan, One World Trade Center in New York, the 2008 Olympics Birds Nest Stadium in Beijing and the cable-stayed Centenario Bridge over the Panama Canal. CSI's software is backed by more than three decades of research and development, making it the trusted choice of sophisticated design professionals everywhere!
