Xii August 2019 000_COVERS.qxd 2/13/1950 7:25 PM Page 3 000_COVERS.qxd 2/13/1950 7:25 PM Page 4 I take this opportunity to congratulate the USBRL team for appreciable work done on the project in the last one year and for bringing out the publication of the 12th issue of this Technical Magazine Himprabhat. The Udhampur-Srinagar-Baramulla Rail Link (USBRL) is a treasure trove of knowledge, new techniques, state-of-the-art technology and varied experience for engineers and is, thus, a unique project in the annals of Indian Railway. The magazine not only provides the details of experience gained during the course of implementation of the project but also provides a platform for the project team to share their views. This is a very commendable effort for documenting the important facets of challenges in the Himalayas for contemporary professionals as well as for posterity. I hope that USBRL maintains the momentum and spirit and continues to move forward in realisation of dreams of connecting Kashmir valley to the Indian Railway network as well as to take forward this fascinating journey of publication of a magazine to enrich all experienced and young engineers alike. I am glad to see the 12th issue of Himprabhat Technical News Magazine giving an account of the achievement of technical marvels and the challenges faced by the USBRL Organisation of Northern Railway. The USBRL team has had a breakthrough in tunneling efforts, excavating 26.34 km in 2018-19 against last year’s progress of 17.05 km, which is 54.5% more compared to last year. Actual expenditure too surged to `2,587 crore i.e crossing `2,500 crore impelling paradigm shift on progress of work. The unprecedented work is being chronicled by publication of Himprabhat. I find that the magazine covers a wide variety of topics and activities enumerating the details of work carried out, the challenges faced and the measures adopted the USBRL team’s initiative and endeavour. The efforts in publication of this magazine are laudable and deserve to be complimented. I am sure the USBRL team will maintain the momentum and spirit this year to surpass the benchmark set up last year and also to continue to chronicle the knowledge and experience by periodical publication of this magazine. The USBRL Rail Link Project was envisioned with a view to provide reliable and efficient mass transportation system and to connect the Kashmir Valley with the rest of Indian Railway network. The 12th issue of Himprabhat lives up to the technical standards that had been laid in the previous issues of the magazine. This issue of Himprabhat captures a rich and varied technical experience of project engineers and international consultants encompassing a wide gamut of activities on tunnels and bridges in the mountainous terrain of Himalayas. I have vivid memories from my last visit on how engineers overcame technical challenges deep inside tunnels or while building piers on steep cliffs facing over deep gorges. It is an endeavour of this magazine to document every innovative work on USBRL for posterity to cherish and learn lessons. It is a matter of pride and huge satisfaction that works on tunnels and bridges are progressing very well. I wish that USBRL takes forth this fascinating journey in the magazine to enrich the knowledge of all engineers.

    INTRODUCTION TO EARTHQUAKE ENGINEERING Earthquake engineering is the science of the performance of buildings and struc- tures when subjected to seismic loading. It also assists analyzing the interaction be- tween civil infrastructure and the ground. One of the most important aims of earth- quake engineering is the proper design and construction of buildings in accordance with building codes, so as to minimize dam- age due to earthquakes. It is the earthquake resonant wave frequencies of seismic engineer who ensures proper design of waves, thus reducing the damaging effects. buildings, so they will resist damage due to Thus, the structure is protected from the earthquakes, but at the same time not be damaging consequences of an earthquake unnecessarily expensive. by decoupling the structure from the shak- ing ground.
