Here are some suggestions from my side..but before following points should be kept in mid:-
* This is only my personal thinking not affected by anyone else
* These suggestions are prepared to improve our forum. I didnt say, our moderators and admin are not working to improve the forum.
* I prepared my these suggestion keeping in mind the effort of those users who are new but contributing a lot and contributing power stuff not just posting to become active.
* I am not an english man and is not pointing out any one with bad english.
* These are just the suggestions, NOT A TRY TO CHANGE THE FORUM BY ONE MAN, many among you will disagree with me, many will agree, some will just agree with some points.
* I do not want to create politics here.
* I love my forum. and beleive in freedom of speech and right to think and express and i will appreciate any criticism and appreciation.
* I know only ADMIN, moderators can change the rules, we are here for suggestions only
* I do not know where my position will be? if these suggestions are implemented fully/partially. and I am not interested in ranking/reputation but it is important for users to get reward for their good work
So here I go,
1) Instead of showing thanks given and thanks received on posts, it should be the ratio of both...
for an example:-
xx thanks given in yy posts sholuld be Thanks/Post ratio = xx/posts = zz
this ratio should be the base for user's popularity....a user with high ratio (zz) means his posts are productive and if this ratio is less than 1 means user is posting but due to lack of quality/information he is not contributing much....
2) thanks given/thanks received ratio is also important....
if this ratio is less than one, it means a user is popular among other users (receing high no. of thanks) but at the same time he is not agreeing with other users or not giving thanks to other users ( as no. thanks given by this users is less). so the ideal ratio should be near UNITY...so that people receive and give thanks....it does not mean that if i receive 20 thanks i must retrun 20 or more thanks back to other users...this ratio is also useful in determining a users activity in forum (with ratio less than one, also means that user is helping others but in return not finding right posts for himself to say give thanks to other users)....
3) the old REPUTATION points should only be awarded by forum ADMIN, MODERATORS or VIPs. It should be disabled for other common users to avoid misuse of reputation points. Only if forum team think that a user must receive reputation point they should award the points.
3.1) Some times REPUTATION should be enabled for other members to vote for moderators or other members. but on rare occasions...for a hint this can be done twice a year like elections... 3.2) Reputation should be equal to the ratio mentioned in point no. 2) plus (+) any reputation recevied from forum team or from point 3.1)
4) A leaderboar should be created. Rankings displayed on main forum page should not be according to total no. of posts or total. no. of thanks rather they should be according to reputation calculated from point 3.2)....this is will be very effective because in this case not only our moderators or only the members with the highest posts will be top scoreres but it will also give the chance to the new users posting very good materials and receving thanks.
Of course I am not denying that our precious active members and mods made very large no. of posts which are also useful.
5) All the details about actual no. of posts and threads and actual no. of thanks received and given should be moved to the profile of individual user. who ever is interested in seeing the total nos. should refer to the detailed profile of that user.
6) All the above point/reputation system recommended by me should be only applicable to posts and threads RELATED directly to the CIVIL ENIGNEERING stuff...
I know our moderators receive points and thanks and reputation based on correcting other members and telling them to abide by rules...yes thats the work of a moderator and he should receive credit for his hard work...and yes they also contribute to the real stuff along with moderating the forum...but there should be another system for the moderators for doing their moderation job. I mean they should be ranked within them selves and there should be another section like MODERATORS POINTS/POPULARITY SECTION....or any thing else...so this way we may exclude our FORUM DISCUSSION (first one) and VARIOUS section (last one) and any other posts in which moderators ask other members to correct their posts etc. from the main point system.
7) Medals should be awarded once a user's points from 3.2) reaches some specific limit. For an example If a user xyz reaches 15 points from 3.2) he should be awarded a medal. These settings can be discussed further. I just want to give you indications not the exact system.
8) The points with DONATE option should be reduced by a factor and added in the repuation points. [/code]total points as said earlier should be move to profile. for an example if i have 1000 points they should be redesigned to normalize them to the magnitude of REPU points in 3.2) or they should be multiplied by a factor say a factor of (250 or 1/250) so that 1000 becomes 1000/250 = 4 and added into the main ranking REPUTATION points.
9) I and we do not believe in language, race, religion etc rather we believe in skills and contribution. but as we are working in ENGLISH language in our forum. so i think we need our FORUM DISCUSSION or atleast the [color=#4682B4]RULES written in good english without grammer mistakes. I my self not an expert in ENGLISH and cant be because i am not an english man. but one should always try to improve. because our RULES section is among the most viewed section so it should be error free yes even from language point of view. Any moderator with good english should be awarded the duty to ammned the RULES section posts for language mistakes. for general engineering posts it is okay to accept lang mistakes as our main concern is about the main concept of engineering not on the language. For good english i mean with no spelling mistakes and clear meaning. it does not mean putting idioms and making understanding difficult bcz most users are not english here.
10) There should be a distinguished medal for experinced users of this forum. For an example DELL BRETT is so experienced in actual life. So after confirming and talking with moderators all these members should be award a special medal for having actual experience displayed with their posts. or atleast we can dispaly no. of years like SHOUT is displayed in each post for each user.
just a correction!
See in this post even, i made some spelling mistakes, although i reviewed it several times before posting and i also made some mistakes about formating color and size...but i didnt see the EDIT button to edit my post to correct it...on some posts i see the EDIT button and some times no..is there any bug...
and the last point after reading the post by chigozie about user BENNYK problem
11) If a member (we may put limit as only the PROFESSIONAL ENGINEER active status) has some issues and want to leave the CIVILEA, we must respect for what he has contributed and there should be an option of RESIGN to leave the forum with respect. after that his name should be displayed with RESIGNED symbol like our RETIRED MODERATORS.

Design of Fiber-Reinforced Polymer Materials for Seismic Rehabilitation of Infilled Concrete Structures
Authors: Ghassan K. Al-Chaar and Gregory E. Lamb
US Army Corps of Engineers
Number Pages: 83
File Size: 1.2 Mb
A recent study by the U.S. Army Engineer Research and Development Center (ERDC), Construction Engineering Research Laboratory (CERL) for the Federal Emergency Management Agency (FEMA) revealed that more than half of the Army buildings located in high or moderate seismic zones did not meet current seismic code requirements and were found vulnerable to damage during an earthquake.
One rehabilitation technique that addresses vulnerabilities in both the masonry infills and in nonductile concrete frames is the use of fiber-reinforced polymer (FRP). ERDC/CERL investigated the effectiveness of such a technique by conducting an experimental program on reinforced concrete (R/C) frames infilled with masonry. Based on this research and related research in the field, this report was developed to provide in-depth guidelines for engineers and practitioners on how to evaluate the strength and stiffness of R/C members and masonry-infilled frames strengthened with FRP.
This document uses the same nomenclature used in ACI 440, Guide for the Design and Construction of Externally Bonded FRP Systems for Strengthening Concrete Structures, when possible. Major contributions that go beyond ACI 440 include guidance on:
• FRP systems that have nonlinear stress-strain behavior
• flexural strength of R/C members fully wrapped with FRP and containing
compression steel reinforcement
• moment-curvature relationships for beams
• compressive strength of noncircular R/C members
• thrust-moment interaction behavior for columns
• strength and stiffness of masonry-infilled frames with FRP overlay
• global structural system performance evaluation using nonlinear pushover
analysis.

The general principles for the identification and classification of soils on the basis of the material and mass characteristics most commonly used for soils for engineering purposes.
EN ISO 14688-2:2006 Geotechnical investigation and testing - Identification and classification of soil - Part 2: Principles for a classification (ISO 14688-2:2004)
This standard establishes together with ISO 14688-1 the basic principles for the identification and classification of soils on the basis of those material and mass characteristics most commonly used for soils for engineering purposes. The characteristics relevant may vary and so, for particular projects or materials, more detailed subdivisions of the descriptive and classification terms may be appropriate.The classification system established in this standard permits soils to be grouped into classes of similar composition and geotechnical properties, and with respect to their suitability for geotechnical engineering purposes, such as: foundations, ground improvements, construction material for roads, construction material for embankments, construction material for dams, construction material for drainage systems.The field of application of this standard is natural soil and similar man-made material in situ and redeposited.

C.Reviews
-------------
"Wiley's latest may lay claim to being the most inclusive - both in breadth and depth - with this excellent reference. Kutz has successfully sought to include more "authoritative discussions, real-world examples, and insightful analyses. It is the addition of this extra text that will find appreciative readers, especially those relatively new to a topic." (American Reference Books Annual, 2008)
