A. One column Layout

This is the default layout of the Twenty Thirteen theme if and only if you do not add any widget in the Secondary Widget area in Appearance > Widgets. Otherwise, the Twenty Thirteen theme will automatically have a two-column layout if you add widget to the Secondary Widget area.
If you want to add widgets in the Secondary Widget area for your site』s pages/posts but would prefer a one-column layout for all BP pages, following are the steps to do so.
1. Create a child theme of the Twenty Thirteen theme.
2. Create a new file in your new child theme folder and name it buddypress.php.
3. Copy over the content of Twenty Thirteen』s page.php file into the new buddypress.php file. Remove the get_sidebar tag just before the get_footer call in the template.

4. Create a blank functions.php file in the folder of your child theme if you don』t have one yet. You will need to remove the .sidebar body class generated if any widget is added to the Secondary Widget Area which would move the alignment of the content area away from the center,
5. Add the following to the new functions.php file then save file.
?1234567891011 $value) {             if ($value == 'sidebar') unset($wp_classes[$key]);        }    endif;    return $wp_classes;}add_filter('body_class', 'mme_remove_sidebar_body_class', 20, 2);

4. Create a blank functions.php file in the folder of your child theme if you don』t have one yet. You will need to remove the sidebar body class generated if any widget is added to the Secondary Widget Area which would show up in regular blog posts/pages,
5. Add the following to your new functions.php file then save file.
?1234567891011 $value) {             if ($value == 'sidebar') unset($wp_classes[$key]);        }    endif;    return $wp_classes;}add_filter('body_class', 'mme_remove_sidebar_body_class', 20, 2);
6. Open up your child theme』s style.css file, add the following and save file.
?1234567891011121314151617.buddypress .entry-header,.buddypress .entry-content,.buddypress .entry-summary,.buddypress .entry-meta {    max-width: 1040px;    width: 100%;} @ media (max-width: 1069px) {    .buddypress .entry-header,    .buddypress .entry-content,    .buddypress .entry-summary,    .buddypress .entry-meta {        padding-left: 20px;        padding-right: 20px;    }}
– delete the space between @ and media in media query above.
7. Upload your Twenty Thirteen child theme folder to server.
C. Two Column, Right Sidebar Layout

When you add any widget to the Secondary Widget Area in Appearance > Widgets using the Twenty Thirteen theme, the right sidebar will automatically show up in all posts and pages including the BuddyPress pages. So if you plan to have the same widgets in the right sidebar throughout the site, then you can stop reading at this point as you will not have to do anything further.
However, if you want to customize the sidebar content of all your BP pages, you can do so by: a) using a plugin like Widget Logic to assign widgets to specific pages by using conditional tags or b) by creating new buddypress.php and sidebar-buddypress.php files and then registering a new widget area in your child theme』s functions.php file. The following steps are for the second option.
1. Create a child theme of the Twenty Thirteen theme.
2. Create a new file in your new child theme folder and name it buddypress.php.
3. Copy over the content of Twenty Thirteen』s page.php file into a new buddypress.php file and remove the section about retrieving the post_thumbnail. Then you will have to change get_sidebar() to get_sidebar(『buddypress』).
