Soft Story Part 2



Soft Story Part 2


Now, let's say we shake the table to the horizontal direction at random and back and forth.
Sekarang, misalkan kita guncang meja tersebut ke arah horizontal secara acak dan bolak balik.

With the same shock, it turns out the two piles of stone have different behaviors.
Dengan goncangan yang sama, ternyata kedua tumpukan batu mempunyai perilaku yang berbeda.

The first pile could have survived during the shaking lasts.
Tumpukan pertama bisa saja masih bertahan selama goncangan berlangsung.

However, a second stack had collapsed due to a layer of "false" bricks in the middle of the pile that did not withstand the thrust of "fictitious" who worked in the lateral and back and forth.
Akan tetapi tumpukan kedua sudah runtuh akibat lapisan batu bata "palsu" yang ada di tengah-tengah tadi yang tidak kuat menahan gaya dorong "fiktif" yang bekerja secara lateral dan bolak balik.

This soft layer of brick can be represented as a soft story.
Lapisan batu bata lunak ini bisa direpresentatifkan sebagai soft story.

If the soft layer is located on the top floor, is certainly not a problem. The problem is if this story is on the soft layer or the bottom floor. And .. Such a fact is often found in the field. Why is that?
Jika lapisan lunak ini berada di lantai paling atas, tentu bukan masalah. Justru yang jadi masalah adalah kalau lantai lunak ini berada pada lapisan atau lantai yang paling bawah. Dan.. kenyataannya memang seperti ini yang banyak dijumpai di lapangan. Mengapa demikian?

Here we try to give two examples of factors that caused the collapse because of the soft story.
Berikut ini kami coba berikan dua contoh faktor yang menyebabkan keruntuhan karena pengaruh soft story

A. Abandoned brick wall stiffness.
A. Kekakuan Dinding Bata Diabaikan.

The buildings such as office buildings, hotels, or apartments, especially in big cities, in general, have a lobby in the basement or ground floor.
Gedung-gedung tinggi yang bertipe gedung perkantoran, hotel, atau apartemen, khususnya di kota-kota besar, pada umumnya mempunyai lobi yang berada di lantai dasar atau lantai ground.

The characteristics of the lobby floor is:
-         Height between floors are usually larger than the typical floors above it. Architects normally want to look bigger lobby, spacious, and magnificent.
-     Due to wide, then on the lobby floor, brick walls using relatively less than in the upper floors that do require a bulkhead walls between rooms.

Ciri-ciri lantai lobi adalah :
-  Tinggi antar lantainya biasanya lebih besar daripada lantai tipikal di atasnya. Arsitek biasanya menginginkan hal ini agar ruangan lobi terlihat lebih besar, luas, dan megah.
-       Karena ingin luas, maka di lantai lobi, penggunaan dinding bata relatif lebih sedikit daripada di lantai-lantai atas yang memang membutuhkan dinding-dinding sekat antar ruangan.
