A detailed seismic performance assessment procedure has been developed
for reinforced concrete frame buildings with masonry in-fill walls and reinforced
concrete frames including shear walls. The procedure uses member damage
functions, in terms of inter-story drift ratios, developed for the primary
components: columns, beams, in-fill walls and shear walls. Analytical
investigations carried out to determine the influence of a number of parameters
on the damageability of components were combined with existing experimental
data to develop component damage functions. A new approach has been
developed to combine component damage states to determine the story and
building level performance states. The procedure has been calibrated and
compared with other procedures by predicting the observed performance of
seven buildings exposed to recent earthquakes in Turkey. It was observed that the
damage experienced by most of the components of these buildings was predicted
satisfactorily, and that the observed building damage states were captured. The
procedure can be used for a reliable performance assessment as well as
performance-based design of the RC frame structures.

The goal of this study is to investigate the collapse risk of reinforced concrete building columns constructed prior to the mid-1970’s, subjected to cyclic lateral loading. These columns have reinforcement details deemed inadequate by modern seismic design standards, and as such are vulnerable to collapse. Testing of two full-scale, shear-critical column specimens was carried out at the NEES-MAST facility at the University of Minnesota. The test specimens had nominally identical material and reinforcement properties. The primary test variable was the applied axial load, which was held constant at 500 kips and 340 kips for the first and second specimens, respectively. The specimens were subjected to increasing lateral displacement cycles until axial load carrying capacity was lost. The thesis discusses the observed lateral and axial load resisting behavior, and analyzes the measured responses of the columns up to and beyond the lateral drift at which they were able to sustain axial load. Test results indicate that column behavior was significantly influenced by the magnitude of the applied axial load, and that the ratio of axial load to gross axial capacity of the longitudinal reinforcement is a key parameter in identifying columns in which axial failure occurs simultaneously with shear failure.

Introduction to Soil Mechanics covers the basic principles of soil mechanics, illustrating why the properties of soil are important, the techniques used to understand and characterise soil behaviour and how that knowledge is then applied in construction. The authors have endeavoured to define and discuss the principles and concepts concisely, providing clear, detailed explanations, and a well-illustrated text with diagrams, charts, graphs and tables. With many practical, worked examples and end-of-chapter and coverage of Eurocode 7, Introduction to Soil Mechanics will be an ideal starting point for the study of soil mechanics and geotechnical engineering.
Currently I took the decision to start some online Primavera P6 tutoring.
Youtube contains many videos related to the topic but I couldn't manage to find a well taught video.
So this led me to ask for some help, since lot of engineers on the site had went through this experience before and had some online tutoring.
Looking forward for some help on this,
Thanks in advance,
