Hi dear friends,
I will appreciate if any body help me who access ACI SPs to share this Proceeding.
Thank you.

Earthquake engineering is the ultimate challenge for structural engineers. Even if natural phenomena involve great uncertainties, structural engineers need to design buildings, bridges, and dams capable of resisting the destructive forces produced by them. These disasters have created a new awareness about the disaster preparedness and mitigation. Before a building, utility system, or transportation structure is built, engineers spend a great deal of time analyzing those structures to make sure they will perform reliably under seismic and other loads. The purpose of this book is to provide structural engineers with tools and information to improve current building and bridge design and construction practices and enhance their sustainability during and after seismic events. In this book, Khan explains the latest theory, design applications and Code Provisions. Earthquake-Resistant Structures features seismic design and retrofitting techniques for low and high raise buildings, single and multi-span bridges, dams and nuclear facilities. The author also compares and contrasts various seismic resistant techniques in USA, Russia, Japan, Turkey, India, China, New Zealand, and Pakistan.

SRS-263 Deflections of reinforced concrete floor slabs
Author: Vanderbilt - Sozen - Siess | Size: 14.5 MB | Format:PDF | Quality:Unspecified | Publisher: University of Illinois | Year: 1963 | pages: 304 | ISBN: NA
This report is one of a continuing series of reports written as part of the investigation of multiple-panel reinforced concrete floor slabs which is currently being conducted at the University of Illinois. The floor slab investigation has as its over-all objective the development of a unified design procedure for floor slabs.

SEISMIC PERFORMANCE OF MULTI-SPAN RC BRIDGE WITH IRREGULAR COLUMN HEIGHTS
Author: Samy Muhammad Reza | Size: 3.3 MB | Format:PDF | Quality:Unspecified | Publisher: THE UNIVERSITY OF BRITISH COLUMBIA (Okanagan) | Year: 2012
Bridges are essential elements in modern transportation network and play a significant role
in a country’s economy. However, it has always been a major challenge to keep bridges safe and
serviceable. Modern bridge design codes include seismic detailing in order to ensure ductile
behavior, which was absent in the pre-1970 codes that made older bridges vulnerable during
earthquakes. The main parameters effecting the performance of bridge (tie spacing, concrete and steel properties, amount of reinforcement) varies significantly from old to modern bridges. The presence of irregularity in column heights is one of the common causes of seismic vulnerability and the non-uniform column height is the most common form of irregularity. In this study, a four span RC box-girder bridge has been considered for different column height configurations. Here, a detailed parametric study has been performed to understand the effects of various factors on the limit states of the individual bridge columns using factorial analysis. Static pushover analyses, incremental dynamic analyses and fragility analyses of bridges with irregular column heights have been conducted to identify the seismic vulnerability of bridges in the longitudinal direction due to irregularity in column height. This study also investigated the difference of conventional force-based approach and displacement-based approach in designing a bridge with irregular column heights. Canadian Highway Bridge Design Code (CHBDC) and AASHTO 2007, like other traditional design codes follow force-based design (FBD) method, which is focused at the target force resistance capacity of the structure. On the other hand, displacement-based design approach focuses on a target maximum displacement of the bridge during the earthquake in a
specific zone. Seismic performances of the bridges designed in two different methods have been compared by non-linear dynamic analyses in the longitudinal direction in terms of maximum and residual displacements and energy dissipation capacity.

PERFORMANCE ASSESSMENT OF SHEAR-CRITICAL REINFORCED CONCRETE PLANE FRAMES
Author: Serhan Güner | Size: 6 MB | Format:PDF | Quality:Unspecified | Publisher: University of Toronto | Year: 2008 | pages: 464
Current analysis procedures for new reinforced concrete structures are typically based on linear-elastic principles. However, under certain conditions, it may be necessary to analyze a structure to more accurately predict its structural behaviour. Such an analysis can be performed using nonlinear analysis procedures which typically require specialized software. This type of software is limited in number and most available programs do not adequately capture shear-related influences, potentially severely overestimating strength and ductility in shear-critical structures. The purpose of this study is to develop and verify an analytical procedure for the nonlinear analysis of frame structures with the aim of capturing shear-related mechanisms as well as flexural and axial effects. A previously developed analysis program, VecTor5, is further developed for this purpose. Originally formulated in the early 1980s at the University of Toronto, VecTor5 is based on the Modified Compression Field Theory (MCFT) and capable of performing nonlinear frame analyses under temperature and monotonic loading conditions. Although providing generally satisfactory simulations, there are a number of deficiencies present in its computational algorithms.

We are so sorry due to last problem in loading Civilea.com website.
Recently we have high load on old server, we decided to upgrade our main server, we migrated to a good and also expensive server at same datacenter, CivilEA is located on this datacenter in last 4 year and we really agree with it, they are expert, famous, friendly company.
Thus we start migrating to next level server, some problem are usual after migration, for example DNS problem. anyway after about 72 hours CivilEA was accessible in all around world. Unfortunately last night our new server crashed and we did not access to server from our location. We shall wait, only staff of datacenter can help us, they start to recover server, this is their last comment:" You were one of the very few clients that suffered a Raid 5 Disk Array failure. " Yes, unfortunately HDD of server crashed, and unfortunately due to latest migration we do not have online back up of forum, this mean we missed some data, unfortunately we backed to data of 5 days ago,We are so sorry for this issue, we worked hard to recover data, we are working non-stop on server during last week.
Our datacenter will report us about last issue in next week,
Be note that we missed data during last 5 days.I am so tired and sad, very bad chance....
some users that registered during last 5 days and also bought subscription plan, need to registered again, then send us their username and also previous payment detail here:
