Overview

In this section we are going to discuss the steps for ingesting building data into a format that MAEviz can understand and use in the building analyses. Before we launch the software, we will go over the MAEviz building data format so that if any changes need to be made, we can make those now.

Data Format

We will need two datasets for running a building damage analysis, a building dataset ingested into MAEviz and a Fragility Mapping dataset ingested into MAEviz. The building dataset will contain columns such as structure type, year built, etc and the fragility mapping dataset tells MAEviz which fragility curves should be used for which buildings.

Building Data

Let's start out describing the building data. The building data for MAEviz needs to be in ESRI's Shapefile format. Below you will find the column names, a short description and the column types that MAEviz requires. Only the column types (e.g. integer, double, string, etc) must explicitly match because when we ingest the dataset, MAEviz will ask you to map your columns to the columns that MAEviz needs. For example, your structure type information might be in a column called s_type and MAEviz expects it to be called str_type so you can tell MAEviz that s_type maps to str_type and thus no changes need to be made to your dataset. I've categorized the columns into three categories: Very Important, Less Important and Least Important.

Building Columns:

Very Important

Field Name

Field Description

Field Type

STRUCT_TYP

General structure type of the building

string

Less Important

Field Name

Field Description

Field Type

OCC_TYPE

Broad HAZUS Occupancy Category (e.g. RES3 - multi-family residential)

string

APPR_BLDG

Appraised value for the building

double

SQ_FOOT

total building area in square feet

integer

DWELL_UNIT

total number of dwelling units in the building

integer

NO_STORIES

total number of stories for the building

integer

CONT_VAL

value of building contents

double

STR_TYP2

detailed structure type as per HAZUS MR-3 specifications

string

EFACILITY

essential facility designation

string

Least Important

Field Name

Field Description

Field Type

PAR_ID

parcel identifier

string

PARID_CARD

improvement identifier

string

BLDG_ID

building identifier (unique)

string

STR_PROB

probability that the structure type specified is correct

double

YEAR_BUILT

the year the structure was built

integer

A_STORIES

the number of above ground stories

integer

B_STORIES

the number of below ground stories

integer

BSMT_TYPE

the basement type

string

GSQ_FOOT

total ground floor area of the building in square feet

integer

OCC_DETAIL

specific occupancy category, describing the detailed use of the building

string

MAJOR_OCC

major occupancy category for the parcel in which the building is sited

string

BROAD_OCC

general occupancy categories

string

REPL_CST

replacement cost for the building from R.S. means square foot cost

double

STR_CST

structural component of the replacement cost

double

NSTRA_CST

acceleration sensitive component of replacement cost

double

NSTRD_CST

drift sensitive component of replacement cost

double

DGN_LVL

design level for the building as per HAZUS MR-3 specifications

string

OCC_TYP2

detailed HAZUS occupancy category for the building

string

TRACT_ID

census tract identifier

string

Now, it's ok if you don't have all of the above information for your buildings since the more detail you have about your building means you can be more explicit in mapping your fragilities to your buildings in the damage analysis. Only in the more advanced analyses will MAEviz start requiring some of those other attributes (e.g. estimating structural damage cost requires the APPR_BLDG column since the cost of the structure needs to be known). However, all of these columns need to be present, even if they contain no data because MAEviz will expect all of the columns to be there. In the next version of MAEviz, this restriction of all columns being present, even with no data, should be eliminated.

Fragility Data

Launch MAEviz

The default installation directory for MAEviz is a folder with the same name, "MAEviz" so you should be able to launch the software by going to Start -> Programs -> MAEviz.
