The source ( point where slip the crust)produce wave of several period but the principals run one streak and another elliptical. The streak wave arrive first that the elliptical wave but the elliptical wave produce more dammage. Besides when the wave arrive to the surface the contact produce...

To absorb energy the structure have to resist the movement of the crust (earth) to do that the period between both (structure and crust) have to be near, in few words the capacity of absorb energy is a funtion of its period, weight (m/g) and rigid (k). If you have more mass and rigidity in one...

According with my studies and reading is impossible warp 7 inches in fire condition without loss their physics and chemistry property of the steel, besides the structural capacity of the building at itself change to worse. The steel is very friendly and god are gradiose but is very dangerous...

You could buy Manual of steel Construction Volume 1 and 2,

Excuse, may you explain more.

Don't lost the alternative with steel sheets and WF or other steel sections.

Hi the book structural steel design chapter 12. Ronald Press Company and chapter 14 of Bresler, Lin and Scalzi Design of steel structure could help. luck

Are you talking abour mansory wall or concrete shear wall? is fine to know because are differences.

I don`t known really what do you expetc in this forum, but your problem is really complex. You have to design a steel structure that support each piece of concrete during the launching, is a special design, where you have to know velocity of the wind, earthquake, dead load, impact, friction...

You have to design the houses agains earthquake. I don't know the magnitude of the wave and the energy dissipate in each blasting. The thumb rule are in hard soil flexible structure in soft soil stiff structure. The reason: period of vibration in the soil never will merge with the period of...

hi, I and sure that with blasting NO, chipping is the way, but also depend of the rock quality. Is bether if you could made a geological study to know more about the rock, if the rock is granite or other hard rock, follow with your idea, if not, you are buying a sue.

Hi, in my oppinion you have to study the problems as all. First the real condition of existing building, wall, foundation, etc. next, the loads ( dead, live, wind, eartquake, after next, analyzes the structural model that you will create and then design the beam of steel, woods or whatever you wish

If you only design at concrete, I wish recommend you RCBE their e mail is RCBEINFO@ACI.COM vertion 5.1.1 is a great software combine vertical load, horizontal load like wind, earthquake.Where you can work with vertical,horizaontal and oblique elements all together. I am sure that is the best of...

Acoording with my knowing your workplace have the reason your have to design the welds take in consideration the stress.

You can prestress or poststress the concrete columns or beams,the idea is introduce compresion stress in addition to be reduce in case the member is submit at tension. The element follow working in compresion before and after the force are applied.
