) ... here you can find my first attempt of creating an excel sheet to assist my calculations for the design of a cold formed column according to EC3.
The analysis has been done with SAP2000, and the Section Designer has been used for the design of the cross section.
I would appreciate your comments, remarks and suggestions.

This edition of the Guide Specifications was developed from the previous Allowable Stress Design (ASD) and Load Factor Design (LFD)-based, edition (AASHTO 1997). An evaluation of available foreign specifications covering pedestrian bridges, and failure investigation reports as well as research results related to the behavior and performance of pedestrian bridges was performed during the development of the LRFD Guide Specifications.

Written for architects, engineers, preservation, and code enforcement professionals, this is the only comprehensive book that examines how the International Building Code (IBC) and the International Existing Building Code (IEBC) can be applied to historic and existing buildings. For ease of use, the book is organized to parallel the structure of the IEBC itself, and the approach is cumulative, with the objective of promoting an understanding of the art of applying building regulations to the environment of existing buildings.
The principles of regulating existing buildings are discussed. Basic building information, nonconforming rights, and the code’s approach to change of occupancy are included. The prescriptive, work area, and performance compliance methods of the International Existing Building Code are analyzed. Each method of compliance is described with regard to its application to particular situations, such as repairs, alterations, and change of occupancy. Examples are provided to show signifi cant code issues.

For those meanless word in the quote report, such as "fc^ _ ? -)-)£. 1 (J„ , a", that because Kasperksy doesn't allow use to copy the text in the repoert, so I have to use some OCR software to capture the text from the repoert, which cause the issue.
I notice there is some link in the thread when I copy the report from Kaspersky and paste here, if the link is not allowed, please help me with it, cause I can't find the edit button here, so I can't edit the thread.
Dear all friends:
If you have any book,Papers,.... about Tainter gate design for dam,please kindly Upload.
your Upload will be high appreciated.
thanks in advance.

This PhD dissertation contains a parametric analysis of typical base isolated bridges. The bridges were located in different soil types and were subjected to three different earthquakes (recorded on soft and medium soils). The work had two main objectives: to asses the effects of the nonlinear behavior of the isolation pads of the bridges on the seismic responses (accelerations, displacements, and pier seismic forces), and to study combined effects of base isolation and inertial interaction due to the presence of flexible foundations.
The analytical models used for the study were selected on the basis of initial evaluation of different models proposed in the literature to represent a bridge structure and to evaluate the isolation pads’ nonlinear behavior. The bridges studied were developed with a three-dimensional model. After completing the studies, 2 degree of freedom models were used to investigate more general trends of the inertial SSI effects for the base isolated bridges.
The results of the work show the efficiency of base isolation pads in improving the seismic performance of bridges in most cases. They suggest that the inertial SSI effects will not be generally important for bridge foundations designed with a factor of safety of 3, with more than one line of piles in either direction since they will be very stiff foundations. But they also showed that for slender piers it is important to carefully evaluate the translations on top of the piers due to the rocking effects of the foundation.

PROBABILISTIC SEISMIC DEMAND ANALYSIS FOR THE NEAR-FAULT ZONE
Author: Reza Sehhati | Size: 4.1 MB | Format:PDF | Publisher: Washington State University | Year: 2008 | pages: 187
Ground motions close to a fault can be significantly influenced by rupture directivity effects. In particular, the effects of forward-directivity may cause severe damage to buildings. These effects have not been clearly addressed in current building codes and engineers still lack specific guidelines as to how to account for forward-directivity effects when determining the seismic hazard for structures. A methodology for probabilistic seismic demand analysis that includes the effects of forward directivity through time domain analysis is proposed in this work. First, the characteristics of forward-directivity ground motions and the structural response to these motions are studied and simplified mathematical representations for pulse-type forward-directivity ground motions are proposed. Intensity Measures for forward directivity ground motions are then proposed based on the simplified pulses. For this purpose, the non-linear dynamic response of three generic multi-story shear buildings to near-fault and ordinary ground motion ensembles was studied using Incremental Dynamic Analysis. Results show that whenever the pulse period of forward-directivity ground motions is close to the first-mode structural period, structural response is controlled by forward-directivity pulses. For these cases, structural response can be predicted using pulse-period and pulse-amplitude as intensity measures.
The principles of Probabilistic Seismic Demand Analysis are then extended to consider the effect of forward-directivity within a probabilistic framework. Structural response to pulse-type forward-directivity ground motions is quantified by means of time-domain analysis of simplified pulses that comprehensively represent all possible pulse-type ground motion scenarios. The hazard due to pulse-type motions is then coupled with conventional spectral domain seismic demand analyses for non-pulse-type ground motions. Results show that the proposed methodology captures more accurately the structural response to pulse-type ground motions than with current methods leading to the prediction of greater hazard for near-fault scenarios. In addition, the proposed method provides a clear guide for the selection of time histories for the design of near-fault structures.
