I have a request to made. I want a spreadsheet on which I can give different levels and cross section values, and then it can generate autocad drawings. Like this zoutube video.

Guide for the Development of Bicycle Facilities, 4th Edition
This guide provides information on how to accommodate bicycle travel and operations in most riding environments. It is intended to present sound guidelines that result in facilities that meet the needs of bicyclists and other highway users. Sufficient flexibility is permitted to encourage designs that are sensitive to local context and incorporate the needs of bicyclists, pedestrians, and motorists. However, in some sections of this guide, suggested minimum dimensions are provided. These are recommended only where further deviation from desirable values could increase crash frequency or severity.
This guide has been updated from the previous guide published in 1999. The fact that new guidance is presented herein does not imply that existing bicycle facilities are inadequate or unsafe, nor does it mandate the initiation of improvement projects. The intent of this document is to provide guidance to designers and planners by referencing a recommended range of design values and describing alternative design approaches.
I need ACI SP-30 as a reference for my one of my job.
And I am in a specific need of following Paper for my reference:
Flexural Crack Control in Structural Slab Systems,” Cracking,
Deflection, and Ultimate Load of Concrete Slab Systems,
SP-30, American Concrete Institute, Farmington Hills,
Mich., pp. 1-41.
The next generation of sustainable buildings will have to be radically different from those of today and will be designed using new approaches to materials that are expressed in this study. Smart materials are one of the components for these new approaches. These new materials, which are integrated with the environment, produce renewable energies, maintain themselves, minimize energy consumption and/or maximize the usage of natural light. The contribution of smart materials in architecture gives architects the opportunity of designing smart buildings with lightweight structures and new building elements that react to environmental conditions. The increasing interaction with the environment also leads architects to the following question: Can these material properties be used for supporting the sustainability of the building? The increase in interaction with the environment could ensure that buildings are more compatible with their surroundings. This compatibility could support ecologically sustainable environments and this is the main idea that this study deals with. The aim of this study is to propose and question the application of smart materials in sustainable architecture.

Design and Construction of Sutong Bridge Foundation
Author: Robert B Bittner, Dr. Osama Safaqah, Xigang Zhang & Ole Juul Jensen | Size: 4.9 MB | Format:PDF | Quality:Scanner | Publisher: Deep Foundation Institute | Year: 2007 | pages: 17
The Sutong Bridge across the lower Yangtze river in China will have, when completed, the longest span and highest towers of any cable stayed span in the world. The foundations for this record setting span will also be record setting. They are located in water depths exceeding 30 m with maximum flows exceeding 3 m/sec. The soil at the site of main pylons consists of layers of silty sand and silty clays extending to bed rock at 270 m below river elevation.

Nonlinear Finite Element Analysis of Solids and Structures
Author: René De Borst , Mike Crisfield, Joris Remmers, Clemens Verhoosel | Size: Unknown MB | Format:PDF | Quality:Unspecified | Publisher: Wiley | Year: 2012 | pages: 540 | ISBN: 0470666447
Built upon the two original books by Mike Crisfield and their own lecture notes, renowned scientist René de Borst and his team offer a thoroughly updated yet condensed edition that retains and builds upon the excellent reputation and appeal amongst students and engineers alike for which Crisfield's first edition is acclaimed.
Together with numerous additions and updates, the new authors have retained the core content of the original publication, while bringing an improved focus on new developments and ideas. This edition offers the latest insights in non-linear finite element technology, including non-linear solution strategies, computational plasticity, damage mechanics, time-dependent effects, hyperelasticity and large-strain elasto-plasticity.
The authors' integrated and consistent style and unrivalled engineering approach assures this book's unique position within the computational mechanics literature.
Key features:
Combines the two previous volumes into one heavily revised text with obsolete material removed, an improved layout and updated references and notations
Extensive new material on more recent developments in computational mechanics
Easily readable, engineering oriented, with no more details in the main text than necessary to understand the concepts.
Pseudo-code throughout makes the link between theory and algorithms, and the actual implementation.
Accompanied by a website

with a Python code, based on the pseudo-code within the book and suitable for solving small-size problems.
Non-linear Finite Element Analysis of Solids and Structures, 2nd Edition is an essential reference for practising engineers and researchers that can also be used as a text for undergraduate and graduate students within computational mechanics.

Author: The City of Amarillo and Panhandle Municipalities | Size: 2.5 MB | Format:PDF | Quality:Unspecified | pages: 33
It is the intent of this publication to provide several methods to comply with the adopted standards of this municipality as well as provide some additional opportunities to conserve energy and ensure sustainability. “The Guidelines are not intended to be Standards, but are guidelines only, reflecting the engineering opinions and practices of the committee members. They in no way replace the basic need for good engineering judgment based on appropriate education, experience, wisdom, and ethics in any particular engineering application.”

The third volume in a series on concrete member design and technology is concerned with the stability of single columns and frames consisting of columns and beams for which design procedures are required. The following sections discuss design aspects in detail: (1) buckling limit state-fundamentals; (2) detailed procedures for columns; (3) particular problems; (4) frame analysis; and, (5) design of slender structures according to the model column method. Appendices cover the finite difference method of analysis; a computer program for the model column method; moment capacity tables and diagrams; and, coefficients defining the value and position of the parabola-rectangle compression diagram. /TRRL/

I just wrote some small simple programs in Matlab to calculate and graph the P-M-M curves for a rectangular column subjected to axial force & biaxial bending moments. The design code is Canadian CSA A23.3-04 concrete design. However, it can be readily modified to suit other codes. The prog can draw a series of 3D P-M-M curves (and a 3D surface plot) according to a specified range of angles (i.e. direction of biaxial moment measured against x-axis). You can change column dimensions (Hx, Hy), concrete strength (fc), number of longitudinal bars (Nb = 4, 8, 12, 16....)...or specify a range of angles (at least 3; ex: THETA = 0:pi/16:2*pi or THETA = -pi/2:pi/16:pi/2...) to test it out.
the link below is for the Matlab zip file (colPMMcurves.zip); unzip 4 files into a folder. Run Matlab R2010a and set the above folder as current working folder. From the folder, double-click RcolPM3D_2 (this one is the main script, the other are just functions) to start it. Enjoy! (another prog for circular columns is also available)
