Hello everybody
I have started to develop excel spreadsheets incorporating design flowcharts. But I dont have flowcharts for latest codes, such as ACI, AISC, AISI, etc.
I have searched the forum we dont have it.
I think it was a good idea, as far as seeing how the results evolve, by being able to follow the intermediate calculations.
Below what I have started long time ago. I would like to do the same
Base Isolation for Seismic Retrofitting of Structures
Author: Vasant A. Matsagar and R. S. Jangid | Size: 0.7 MB | Format:PDF | Quality:Unspecified | Publisher: PRACTICE PERIODICAL ON STRUCTURAL DESIGN AND CONSTRUCTION | Year: 2008 | pages: 175 - 185
Analytical seismic responses of structures retrofitted using base isolation devices are investigated and the retrofit schemes are illustrated. The retrofitting of various important structures using seismic isolation technique by incorporation of the layers of isolators at suitable locations is studied. Three specific structures such as historical buildings, bridges, and liquid storage tanks are selected to investigate the effectiveness of the base isolation in seismic retrofitting. Different types of isolation devices, such as elastomeric bearings and sliding systems are evaluated for their performance in the retrofitting works. The response of the retrofitted structural system is obtained numerically by solving the governing equations of motion under different earthquakes and compared with the corresponding conventional structure without any retrofit measures, in order to investigate the effectiveness of base isolation in retrofitting of structures.

The field application of fiber-reinforced polymer (FRP) composite materials as reinforcement for concrete structures has been growing rapidly in recent years, mostly with interest in alternatives to steel reinforcing bars and for strengthening concrete structures. FRP products provide options and benefits not available using traditional materials.
As a result of the extensive use of FRP as internal and external reinforcement for new structures and strengthening concrete structures, respectively, ACI Committee 440 organized three technical sessions on “Field Application of FRP Reinforcement—Case Studies” with a total of 21 papers presented at the ACI Fall 2003 Convention in Boston, Mass. All papers deal with case studies and demonstration projects to provide clear evidence of the practicality, credibility, and maturity attained by this technology.
This volume includes the papers presented during the Fall 2003 Convention, plus five additional papers that augment the range of field applications and case studies. The goal of this document is to help practitioners implement FRP technology, while providing testimony that design and construction with FRP material systems is rapidly moving from emerging to mainstream technology.

Recommended Design Practice for Pile Foundations in Laterally Spreading Ground
Author: Ashford, Scott A.; Boulanger, Ross W.; Brandenberg, Scott J. | Size: 1.60 MB | Format:PDF | Quality:Original preprint | Publisher: Berkeley: University of California, Berkeley, Pacific Earthquake Engineering Research Center | Year: 2011-06 | pages: 68
Recommended design practice for pile foundations in laterally spreading ground
Ashford, Scott A.; Boulanger, Ross W.; Brandenberg, Scott J.
PEER-2011/04, Berkeley: University of California, Berkeley, Pacific Earthquake Engineering Research Center (PEER), 2011-06, PDF (400 P33 2011-04)
This report presents recommended engineering procedures and practices for the analysis, design and performance evaluation of pile foundations for bridges in areas subject to lateral spreading hazards that are based on a synthesis of research findings when supporting research is available, and on the professional opinions of the Principal Investigators when supporting research is lacking. The scope of the report is to summarize those recommendations in a concise document that provides references to supporting materials and/or identifies areas where supporting materials are lacking.

The study developed a self-compacting hybrid fiber reinforced concrete (SC-HyFRC) composite. Optimized specifically for bridge columns, this composite flows under its own weight, completely filling the formwork and achieving full compaction without internal or external vibration. In addition, this SC-HyFRC provides enhanced ductility, shear resistance, and damage tolerance compared to conventional fiber-reinforced composites. To investigate the seismic performance and post-earthquake damage resistance of bridge columns composed of SC-HyFRC, two 1:4.5 scale column specimens were built and tested statically under uni-directional cyclic loading. In both specimens the volumetric transverse reinforcement was 0.37%, which is two to three times less than that of typical Caltrans bridge columns. Both specimens attained large drift ratios of up to 11% without losing axial load carrying capacity and were successful in resisting damage due to spalling of concrete up to drift ratios of 3.6%. Compared to a conventional reinforced concrete column of same dimensions, longitudinal steel ratio, and axial load ratio, the SC-HyFRC columns exhibited superior damage resistance and better load carrying capacity despite a 50% reduction in transverse reinforcement.

Mechanics of fiber reinforced bearings
Kelly, James M.; Calabrese, Andrea
PEER-2012/101, Pacific Earthquake Engineering Research (PEER) Center, University of California, Berkeley, Authors retain copyright, 2012-02, PDF (400/P33/2012-101)
The report contains the findings of a study on the mechanical behavior of unbonded fiber-reinforcedbearings (FRB). Typical FRBs consist of several layers of rubber that are bonded to fiber reinforcing sheets. The purpose of the reinforcement is to prevent the rubber from bulging laterally under compressive load. The most important aspects of these bearings are (i) they do not have thick end plates; (ii) they are not bonded to the top and bottom support surfaces; and (iii) their reinforcements are very flexible. These aspects may seem to be design deficiencies, but they have the advantage of eliminating the presence of tensile stresses in the bearing by allowing it to roll off the supports when it is sheared. This reduces the typical bonding requirements. The weight and the cost of isolators is reduced by using fiber reinforcing, no end-plates, and no bonding to the support surfaces, offering a low-cost lightweight isolation system for developing countries. This work is the comparison between an approximated linear elastic theory and the outputs of finite element analyses.

Properties of Concrete Using Crushed Brick as Aggregate
Author: Ali A. Akhtaruzzaman and Abdul Hasnat | Size: ?? MB | Format:PDF | Quality:Unspecified | Publisher: Concrete International, Volume: 5, Issue: 02 | Year: February 1, 1983 | pages: 58-63
Abstract:
Four grades of concrete made with crushed brick as aggregate were tested to determine their physical and mechanical properties. Nominal compressive strength ranged from 2000 to 5000 psi (13.8 to 34.5 MPa). Test results compared favorably with those for normal weight concrete as obtained from the ACI code equations. In general, for the same grade of concrete the modulus of elasticity is about 30 percent lower and tensile strength is about 11 percent higher than normal weight concrete. Empirical equations predicting modulus of elasticity and tensile strength of brick aggregate concrete have been derived. Brick aggregate can be used to produce high-grade quality concrete. The unit weight is about 125 to 130 lb per ft3 (2000 to 2080 kg/m3). As the properties of brick aggregate concrete lie between those of normal weight and lightweight concrete, it may be classified as medium weight concrete.
