ACI_Check of Max. Crack width for M & N for both Rec. & T sections_ DAR excel sheet
NOTE:
the sheet is perfect for calculating crack width, (my opinion ) is to compare the calculated w cr value with the given in ACI 224r-01, (Table 4.1—Guide to reasonable* crack widths, reinforced concrete under service loads). in my copy i replaced the table at the end of the sheet with ACI 224r-01, (Table 4.1)

Second Order Effects of Gravity under Horizontal Earthquake Load and Preventive Measures
Author: Wen-jie Niu | Size: 0.48 MB | Format:PDF | Quality:Unspecified | Publisher: INTERNATIONAL JOURNAL OF CIVIL AND STRUCTURAL ENGINEERING Volume 2, No 4, 2012 | Year: 2012 | pages: 7
Building only with shallow foundation may overturns under earthquake load. This paper
intends to investigate the building overturn principle and adopt fundamental measures to
prevent such dangers. After consider the building self-weight P.∆
effect(Second order
effect) and take the building as research object, one can find that if we increase building
foundation width and decrease building height , resistant moment R M can be larger than overturn moment o M at the rotating beginning. And the building is safe. Another way to increase the building overall stability is to use raft pile groups which are common method to prevent the overturn of building. There are two possible combined stress groups on the surface between piles top surface and building foundation bottom surface. One is compressive stress and shear stress when the earthquake acceleration is not too large. The other is tensile and shear stress when the earthquake acceleration is extremely large. To ensure the safety of the building, professional engineers can design the pile-raft connections stress not to exceed the allowable combined stress.

Seismic Analysis of High-Rise Building by Response Spectrum Method
Author: Prof. S.S. Patil, , Miss. S.A. Ghadge, , Prof. C.G. Konapure, , Prof. Mrs. C.A. Ghadge | Size: 0.53 MB | Format:PDF | Quality:Unspecified | Publisher: International Journal Of Computational Engineering Research (Ijceronline.Com) Vol. 3 Issue. 3 | pages: 8
This paper describes seismic analysis of high-rise building using program in STAADPro. with various
conditions of lateral stiffness system. Some models are prepared that is bare frame, brace frame and shear wall
frame. Analysis is done with response spectrum method. This analysis will produce the effect of higher modes
of vibration & actual distribution of forces in elastic range in a better way. Test results including base shear,
story drift and story deflections are presented and get effective lateral load resisting system.

With the rapid population growth and dynamic economic developments, the demand for residential, mixed use
and commercial buildings has been increasing significantly all around the world. Due to the excessive increase
in height of buildings in this era, there is a significant impact on the methods used to analyze and design of tall
buildings. There is a clear acceptance within the engineering community that the specifications given in codes of
practice are not suitable for very tall buildings.
General concepts, current methods of analysis and seismic performance of super tall buildings are reviewed in
this paper. Further the effect of higher modes on the performance of super tall buildings is also discussed.
During the last few decades, the application of new techniques and of new mechanical means was
witnessed in virtually every human activity. It became clear in time that the innovation in architecture
would come from those who grasps the possibilities of the new materials and techniques. The present
day, construction of super tall buildings have become a trend and the impetus behind the surge of
these tall buildings has been the need to satisfy the growing demand for office and apartment space.
The convenience of having all of the services one needs in a single building is now becoming a reality
with mixed-use buildings; some of these buildings may also bring the prospect of being able to live
and work without leaving the building. Further the value of time and the high cost of gasoline may be
part of the economic drivers that have sparked renewed interest in urban living and a return to the
central city or downtown areas of many cities, which is a reverse trend from living in the suburbs as in
the past. Due to this new technology towards super tall buildings, engineering judgment has to be
made carefully.

MULTI-HAZARD DESIGN OF MID- TO HIGH-RISE STRUCTURES
Author: ELISA Y. CHEN | Size: 2.6 MB | Format:PDF | Quality:Unspecified | Publisher: University of Illinois at Urbana-Champaign, 2012 | Year: 2012 | pages: 101
The importance of multi-hazard design of structures has emerged in the last decade, as extensive media coverage of natural disasters have increased public awareness of the catastrophic damage that hurricanes and earthquakes can wreak on buildings and infrastructure. Current design codes treat hurricanes and earthquakes as completely independent, which, while true in the physical sense, does not account for the increased risk to structures in regions where both hazards are present. The application of multi- hazard design to mid- to high-rise structures is advantageous, as they have the potential of being governed by either load and have high costs and large occupancy. This study, which develops multi-hazard design, is essential for improving the safety of structures, reducing building life cycle costs, and increasing efficiency in design.
Presently, experts in the fields of seismic and wind structural engineering conduct research autonomously and possess only basic knowledge in the other area of study. To encourage an interdisciplinary approach to multi-hazard design, this thesis presents a comprehensive review of the characteristics of hurricanes and earthquakes along with an explanation of how physical features of the hazards are represented in design codes. With a knowledge baseline established, an analytical model representing earthquake design and one representing wind design can be created and assessed for structural behavior under various loading. With the use of eigenvalue, static pushover, and dynamic time history analyses, it is possible to evaluate the structural response of each model to wind and earthquake loading and compare the behavior of each at a global, intermediate, and local level.
Results of this thesis research show that structural response differs significantly for buildings designed for different hazards. Wind designed buildings are more flexible than those designed for earthquake due to lower lateral load demands, however earthquake designed structures have much greater strength and ductility due to its capacity for substantial plastic hinge development before structural failure. The findings on the variation in structural behavior from the analyses provide a unique understanding of the effects of wind and earthquake is necessary for the advancement of multi-hazard design.

Lateral movements in composite high-rise buildings under Seismic Action
Author: T. Fatima*, S. Fawzia* and A. Nasir** | Size: 0.32 MB | Format:PDF | Quality:Unspecified | Publisher: Queensland University of Technology , 2 George Street, Brisbane, QLD 4000 | pages: 8
Daring human nature has already led to the construction of high-rise buildings in naturally
challenging geological regions and in worse environments of the world. However; literature review
divulges that there is a lag in research of certain generic principles and rules for the prediction of
lateral movement in multistorey construction. The present competitive trend orders the best possible
used of available construction material and resources. Hence; the mixed used of reinforced concrete
with structural steel is gaining prevalence day by day. This paper investigates the effects of Seismic
load on composite multistorey building provided with core wall and trusses through FEM
modelling. The results showed that increased rigidity corresponds to lower period of vibration and
hence higher seismic forces. Since Seismic action is a function of mass and response acceleration,
therefore; mass increment generate higher earthquake load and thus cause higher impact base shear
and overturning movement. Whereas; wind force depends on building exposed, larger the plan
dimension greater is the wind impact. Nonetheless; outriggers trusses noticeably contribute, in
improving the serviceability of structure subjected to wind and earthquake forces.
