Conference Paper

There is no doubt that the heritage of nations represents a lamp through which the causes of advancement and the causes of backwardness are known. The student of Islamic heritage finds a scientific renaissance in the Arab countries after the revelation of the Noble Qur’an and the spread of Islam made the Arabs the reference in all sciences. But the...

A common approach in resisting lateral forces is the use of reinforced concrete shear walls in buildings. These walls represent the main elements to resist the lateral forces due to their large strength and stiffness. However, such walls may contain many openings due to functional requirements, and this may largely affect the overall lateral stiffn...

Sumatra earthquake (2004) and Japan earthquake (2011) shifted earth’s axis by (7cm) and (17cm) respectively. [1] Al-Qasem and Touqan suggested different solutions to the problem in their paper titled “Importance of Returning Earth Axis to Its Original Direction”. Their solution was enlightened from the holy Quran. Surprisingly their first solution...

يقوم التحليل الهندسي على ثلاث قوانين رئيسة: قانون أقدار المادة stress-strain relationships وقانون التوازن equilibrium وقانون التوافق compatibility. ولتحقيق هذه القوانين لا بد من وجود نظام رياضي ثلاثي الأبعاد 3D يشابه الواقع. غير أن قدرة الإنسان المحدودة على معالجة عدد كبير من المتغيرات جعلته عاجزاً عن تحقيق ذلك مما دفعه إلى وضع العديد من الفرضيات و...
Conference Paper
Full-text available
Conflicting assumptions exist between structural engineers (who assume flexible structures on rigid block foundations) and geotechnical engineers (who assume flexible foundations supporting rigid structures). Thus a soil-structure interaction is a step that removes many of the assumptions and thus clears reality to a greater extent. However such a...

Sumatra earthquake (2004) and Japan earthquake (2011) shifted earth’s axis by (7cm) and (17cm) respectively (CNN, 2011) see Figure (1). This shift led to push the northern part of the earth – the part where most worlds' population lives- to the south. The northern part thus enters to the more vulnerable area in respect to the sun. Some of the measu...
Conference Paper
ظاهرة الإختلاف في خلق الله ظاهرة كونية مرئية في اختلاف الليل والنهار والألسنة والألوان وغيرها أرادها الحق سبحانه رحمة للعالمين: قُلْ أَرَأَيْتُمْ إِنْ جَعَلَ اللَّهُ عَلَيْكُمُ اللَّيْلَ سَرْمَدًا إِلَى يَوْمِ الْقِيَامَةِ مَنْ إِلَهٌ غَيْرُ اللَّهِ يَأْتِيكُمْ بِضِيَاءٍ أَفَلَا تَسْمَعُونَ(71) قُلْ أَرَأَيْتُمْ إِنْ جَعَلَ اللَّهُ عَلَيْكُمُ النَ...

God's creation of heavens and Earth is characterized by creator's knowledge which covers everything , his soul tying him with the creatures and his wisdom achieving enhanced balance with time. Current science is characterized by innovation and imitation of God's creation. However, it evolved independently of a universal reference resulting in probl...
Conference Paper

تميز خلق الله سبحانه للسماوات والأرض وما بينهما (للعالمين) بانفراد الخالق بعلمه وبإحاطته بكل شيء علماً، وبروحه التي ربطت بينه وبين خلقه، وبهدايته التي يُسيّر بها خلقه ويربيهم بحيث لا يطغى عالَم على آخر. وبذلك كان خلقه إبداعاً يستحق التقليد. وقد تميز العلم المعاصر الذي يقوده الغرب في إبداعه في استقراء وتقليد خَلْق الله سبحانه في السماوات والأرض. غير...

The presence of mass and stiffness fixed points in the frequency responses of vibrational systems may greatly affect the design of these systems. In this paper, the physical reason for the occurrence of mass and stiffness fixed points and the relationship between them and the phenomenon of internal absorber are investigated. It is found that the fr...
Article
Present methods of analysis and mathematical modeling contain so many assumptions that separate them from reality and thus represent a defect in design which makes it difficult to analyze reasons of failure. Three dimensional (3D) modeling is so superior to 1D or 2D modeling, static analysis deviates from the true nature of earthquake load which is...

The inclusion of a soft storey in multistory concrete buildings is a feature gaining popularity in urban areas where land is of exorbitant cost. In earthquake prone zones, this feature has been observed in post earthquake investigations. Although engineers are prepared to accept the notion that a soft storey poses a weak link in Seismic Design, yet...
Article
Full-text available
Building structures with a soft storey are gaining widespread popularity in urban areas due to the scarcity of land and due to the pressing need for wide open spaces at the entrance level. In earthquake prone zones dynamic analysis based on the Equivalent Static Lateral Load method is attractive to the novice and the design codes leave the choice o...
