perangkat utilitas berguna bagi debian linux user

di netbook sya pake winOS udah bawaan, applikasi untuk modem 3g diperlukan saat ingin register unlimited melalui sms. cukup tancapkan lalu auto install. Berbeda saat menggunakan debian based linux (ubuntu) cukup mudah sih saat instalasi dan mau konek, namun saat ingin menggunakan sms dan mengecek quota jadinya gak bisa. coba cari aplikasi, dapet bernama Betavine Connection Manager, sebenarnya ini awalnya untuk modem Vodafone namun kelanjutannya juga bisa buat general usb modem GSM/3G.

.

.
instalasi cukup sederhana (from::Nicholas Herriot,2010), copast text berikut aja di console

sh -c 'wget http://www.betavine.net/repository/bcm_lucid_install.sh -O /tmp/bcm.sh && /usr/bin/xterm -e sudo sh /tmp/bcm.sh'

personal CAD (editor/viewer) di Linux

saat ini sudah ada program CAD cukup close dgn aCAD/iCAD bernama DraftSight keluaran dari Dassault Systemes yg sudah lebih dulu dikenal dgn CATIA dan SolidWorks nya. Walu masih Beta version namun dapat berjalan cukup stabil di Linux Ubuntu 10 sya, karena menurut sebuah sumber menggunakan C++/QT yg dapat native berjalan disemua sistem operasi Win/Ux/Mac. Penginstallan nya juga cukup mudah karena sudah berbentuk paket deb/rpm. Terlihat sedikit berbeda saat setting gambar dan file keseluruhan, mengunakan tree browser yg tersedia dalam satu main menu OPTIONS - Drawing Styles.



berikut beberapa snapshotnya pda saat pertama kali sya install dan gunakan,

Paket software installasi debian berkisar ~70mb, dapt didownload lewat website sumbernya langsung, DraftSight. perlu koneksi internet untuk aktivasi gratis sebelum 30hri.



skrg sketch gmbar teknik jadi bisa dilakukan di linux dgn akurasi dan kemudahan bagi yg sdh familiar dg aCAD/iCAD waktu jman skul dlu.

balok baja dgn btg tarik

balok baja dgn batang tarik dapat berupa rod+turn buckle dan/atau strand prategang.

ditinjau yg paling sederhana yaitu tanpa prategangan





terlihat tidak berbeda signifikan pada distribusi tegangan, yg sedikit berbeda terlihat pada Mcr tinjauan tekuk torsi lateral.







perlu menggunakan strand dan pemberian prategang agar batang tarik bekerja secara optimal, menuntut teknologi dan alat yg lebih dibandingkan batang tarik biasa.





required hi-tech prestressed equipment, out of my interested areas.

quad mesh yg auto pd SAP2000

SAP2000 versi terbaru mempunyai fasilitas auto meshing jenis linear unstructured quadrilateral mesh. element ini lebih baik dari linear triangular, terutama pada permasalahan lentur.



.



namun terlihat kurang stabil, seringkali gagal pada jenis object berlubang linkaran lainnya.

tampilan persamaan dgn TEX di WP n Goo

sdh dri beberapa waktu lau Wordpress sudah mendukung tampilan persamaan (rumus) dgn engine LATEX di servernya yg kemudian diconvert ke PNG, berikut contohnya

$latex A_s = \frac {1}{4} \cdot \pi \cdot d^2$

diatas untuk menuliskan, untuk mengetahui code yg digunakan arahkan cursor di image diatas lalu akan keluar tooltips.

bagaimana dgn penulisa rumus yg memuat beberapa baris, WP ternyata ngga mampu parsing.

$latex \begin{align}

A_s & = \frac {1}{4} \cdot \pi \cdot d^2 \\

& = \frac {1}{4} \cdot 3.14 \cdot 16^2 \\

& = 201.06 mm^2

\end{align}$

 

$latex \begin{array}{rcl} (x+y)(x-y)&=&x^2-xy+yx-y^2\\ &=&x^2-y^2;\\ (x+y)^2&=&x^2+2xy+y^2& \end{array}$

namun tak semudah yg diperkirakan, rumus yg dapat ditampilkan hanya dalam satu baris saja beda dgn LaTeX beneran  yg terinstall atau yg online,

model struktur shell menggunakan dxf CAD

Pemodelan struktur shell yg bukan pesegi akan cukup rumit jika menggunakan GUI sap2000 cara lain yg cukup mudah adalah menggunakan fasilitas import DXF model dibuat dgn program AutoCAD atau IntelliCAD. Disini dijelaskan langkah-langkah pemodelannya, secara garis besar :

  1. Pada program CAD, buat garis bantu face yg akan dibuat.

  2. Partitioning dgn mengikuti element shell quadrilateral.

  3. Generate surface tiap bagian dari struktur shell.

  4. Buat layer baru dgn nama sembarang untuk object face yg dibuat.

  5. Export gambar dgn pilihan DXF

  6. 5.Pada program SAP2000, tentukan unit sesuai model awal serta pilih blank pada new model wizard.

  7. Import file DXF dgn pilih nama layer yg ditentukan awal.

  8. Setelah model berhasil di import dan tampil, select all lalu lkukan merge node dgn toleransi tertentu.

  9. Test apakan sudah bekerja dgn baik, tentukan kondisi batas (tumpuan dan beban), material & shell element properties.

  10. Run analysis, perhatikan deformasi dan kontur tegangan apakah sudah terlihat continue.


Dibawah ini gambar berikut catatan keterangannya.

Partisi dari lingkaran diameter D = 6.0m


Lakukan mirror dari 1/4 segment model partitioning lingkaran


Ulang untuk menyelesaikan pembuatan lingkaran penuh



ubah User Coordinat System, buat garis ketinggian H = 3.0m kemudian lakukan copy


Buat layer baru dgn nama "face" dapat aktif ditampilkan dan tidak




Generate surface dari empat garis tepi.



Rujukan pemodelan surface (ProgeCAD, 2008)



ulang untuk semua bagian partitioning struktur shell



Setting pias pembagi sisi satu dgn sisi lainnya


Tentukan satuan lalu pilih "blank" template


Menu file pilih import, lalu pilih AutoCAD .dxf File


Tentukan sumbu tegak pada DXF file yg telah ditentukan awal.



Pilih layer object Shell yg telah ditentukan saat pemodelan CAD


Done, object sudah berhasil di import dari DXF



Select All, lakukan merge nodes



Test model dgn penerapan kondisi batas (beban hidrostatis, tumpuan) dan properties (material&element), kemudian running.



Terlihat kontur momen sudah terlihat menerus tidak patah-patah yg berarti element quad shell sudah saling terhubung.


.

Dibawah juga diberikan contoh model lain, yg cukup beberapa step jika menggunakan CAD dan fasilitas import SAP2000.
